AITAH for Thinking There’s a Hidden Affair Between My Husband and Best Friend?

A wife wakes up drunk at her best friend’s birthday bash, hears moaning in the night, and finds her shirtless husband sneaking back to bed—now she’s torn between trusting his bathroom excuse or imagining the worst betrayal. The suspicion gnaws at her marriage, especially since her outgoing friend has a history of flirting with the very man who claims to despise her.

At the same time, the husband has repeatedly flagged discomfort with this “bestie,” only for his wife to brush it off and push more interactions. Beyond that, gym sessions and tequila-fueled parties blur lines, fueling jealousy rooted in old college insecurities. What makes it even more complicated is the lack of hard proof, leaving doubts to fester alongside a fresh update about secret Facebook messages.

‘AITAH for Thinking There’s a Hidden Affair Between My Husband and Best Friend?’

College-era dynamics plant seeds of doubt as one friend shines bright while the other fades into the background.

Update: I later found out that they have chatted a few times through Facebook Messenger. I don’t know what to think anymore.

The breakdown in trust in a marriage often stems from a disregard for boundaries, turning small flirtations into major crises. The wife, racked by insecurities from feeling overshadowed since college, dismisses her husband’s constant discomfort with Maria’s advances—at dinner parties, the gym, etc.—and puts decades of friendship ahead of her partner’s feelings. At the same time, Maria’s promiscuous past and single status stir up jealousy, while her husband’s tolerance turns to anger after the drunken partying incident. The opposing parties see the wife as enabling, forcing intimacy despite warnings, as opposed to what she sees as harmless loyalty.

Additionally, social norms pressure women to maintain “best friend” relationships, but therapists emphasize that dismissing a partner’s insecurities breeds resentment. As relationship expert Esther Perel notes, “Infidelity is not just a physical betrayal, it’s also a betrayal of the ears—when one partner stops listening to the other’s weaknesses” (source: “The State of Affairs,” 2017).

Complicating matters further is the recent news of hidden text messages, which amplify suspicions without evidence, highlighting how unchecked third-party activity can erode even solid alliances.

These are the responses from Reddit users:

The online horde unanimously torches the wife for sidelining her husband’s red flags, insisting Maria’s no friend and the marriage needs a Maria-free zone—stat.

  1. You actually deserve to get hosed ..
    Your hubby saying he was uncomfortable is actually him saying he was attracted to her but kept his distance ..you let her get close and she flirted heavy..He can only shrug off her for so long before temptation gives in..
    You heard moaning and they probably were screwing but taking a chance considering you are in the next room and friends are sleeping over..but maybe it was planned by her to get you drunk and passed out and she was left with him before bed and probably kissed him and he finally gave in to temptation..
    But you should have done was take his underwear off and tasted him to see if he smelled like her vajaja..seriously..
    But what you can do now is go to workouts with him at different times than your friend..
    Or change gyms..
    Work on losing weight and becoming more desirable
    Also stop spending time all together..just visit her by yourself but back off on the relationship

    Also i woukdnt totally trust them so watch his phone and put up a ring camera and nanny cams in the house so if she ever comes over without you there you can instantly come home to stop it..
    Also they coukd sneak off so put a tracker in his car or get the free app life 360 and put it in his car on and another phone
    It alerts you to where the address is and how long the vehicle is there for
    What they did was probably a one tine thing but reading his phone every night will show you if they talk about that night or flirt or just casual talk..
    Tine to take weekend trios and do everything to keep him interested
    I would only spend time all together once every couple months if possible
    But the least he sees her ..
    But if they can’t stay away from each other then you will be prepared especially if he takes days off for being sick but actually spending his time at her place.. its so easy to start sometthing without you knowing..I woujd also leave a nanny cam hidden in her place ..either by her front door under shelter so if he came over you woukd know..
    I’m petty that way but good luck
    So if caught who is going over the cliff probably her..jk

  3. That would be the day when my hubby sits beside your friend and not you..He didn’t even move to sit with you..
    I ever saw flirting it would be shut down instantly
    She wants him and probably has stolen him ..only time will tell
    But secret messaging is a recipe for disaster

  5. YOUR HUSBAND IS A LIER AND CHEATER..
    I’m a guy and this us my point of view
    The years he has known her he just has been casual friends she is gorgeous with a nice figure and honestly any guy will say they don’t like her but underneath you can’t help but be attracted to her..
    This story has been on here numerous times but changed quite a bit..
    But here we go
    When you went to her bedroom in the morning were her clothes thrown all over or in a pile and was she sleeping nude and where were her pajamas ..we’re they on the floor or was she wearing them..
    If she was in her pajamas nothing happened..if her clothes were in a pile then she took them off ..if scattered then they were taken off in passion or lust..
    Now being at the party why was he sitting beside her if he was always saying he was uncomfortable there woukd ‘ve no way I woukd be sitting beside her instead of my ..HELL NO
    This alone sounds fishy
    But drinking alot and her rubbing her hand on his thigh ..I bet he was dying inside and had a major boner thinking all he wanted to to fuck her ..bet he had to relieve himself at least once during the night because he was ready to burst his pants and explode..the heat from her hand must have been driving him insane..
    I think the night was lust and it came to a head and he coukdnt resist any longer from all those months of flirting..
    So you went yo bed early but he of course we decided to stay up why who knows..so you dont know how long they stayed up
    You wake up in the middle of the night to hear moaning..that sounds like they are going at it..
    But you make a noise so the moaning stops and you hear opening and closing a door..
    Then you see him sweaty in the hallway
    He says he went to the bathroom
    I believe he took his shirt off and then decided to go to the bathroom..so whether she told him to come to her room or they met up in the hallway you will never know..but the months of flirting and him getting feeling he coukdnt resist..
    So if he was telling the truth you woukd have heard a door open but not close because we don’t close the bathroom door when we leave..he also woukd have wiped his chest down with a cloth or towel if he was sweaty and hot..
    But he left in a hurry be ause he didn’t want to get caught..
    So it’s the opening and closing of the door that makes me know he is GUILTY…as f.ck
    He didn’t take all his clothes off so he probably tasted her on the edge of the bed and tucked her from the edge while she was probably on her knees
    If she was majority drunk she won’t remember too much but she will know they did the nasty and they will be talking about it and maybe talking about meeting up again or saying it was a one timescale.. but he has had a taste so I think he wants more
    I also don’t think she is going to let up and let him get away ..she wants him
    All you can do is look at his phone every night to see what they say to each other and change places or times of workouts or go where he works out instead of yoga..
    Don’t spend anymore time all together
    You need to spend less time together with her
    If she asks why just say be ause of the night we were all drinking and I’m not sure what happened
    So its easier to spend time apart for now
    All you can do is what Cherie said and set up nanny cams in your place in case she comes over..also another phone in his trunk and use the free app life 360..or find my phone to keep an eye out
    If they want more from each other then these two ways will get them caught..
    My wife says she would put sleeping pills in his drink and while he is passed out I woukd be on his phone messaging her saying we have to stop communicating or a bit be ause you are watching him like a hawk..also say he is sorry but not sorry about that weekend..then wait for the response…
    Wife also said she woukd also do the same to the friend when she passes out use her phone to be suggestive and say I wonder if you miss the way I taste..
    The less thry see each other the easier it will be to get over her
    As wife says you let this happen because you didn’t shut down the flirting

  7. IF HE WANTS NOTHING TO DO WITH HER THEN WHY IS HE MESSENGING HER..
    They have feelings for each other so your job is to keep them apart and don’t let him know you are looking in his phone..they will make a mistake sooner or later..
    He had balls to screw her while you were in the other room..that alone was probably the first time maybe and he coukdnt resist any longer
    But as Cherie or Bob said use other devices to be your own detective.
