AITA for uninviting my best friend from my wedding because she kept telling people she dated my fiancé first?

A woman who has known her best friend since birth is heartbroken after uninviting her from her upcoming wedding. The friend (Izzy) went on a few dates with the woman’s fiancé (Jake) years ago but wasn’t interested. When the woman later started dating Jake, Izzy gave her blessing and even joked about it. But after the engagement, Izzy’s “jokes” turned into repeated public comments that Jake “dated her first” and she “let” the woman have him.

Despite multiple requests to stop, Izzy continued — even at a family dinner. Feeling disrespected and hurt, the woman uninvited her. Now Izzy is upset, and mutual friends are taking sides, calling the woman dramatic for “ruining a lifelong friendship.” Is she the asshole for enforcing her boundaries?

The two women have been friends since birth:

Izzy dated Jake briefly years ago:

The “jokes” escalated after the engagement:

The final straw:

Boundaries in friendships are essential, especially around major life events like weddings. Repeated “jokes” that diminish someone’s relationship — even after being asked to stop — are disrespectful and can indicate underlying jealousy or insecurity. The friend’s behavior escalated from lighthearted comments to public undermining, which crossed a line.

Uninviting someone from a wedding is a serious step, but it’s justified when the person refuses to respect the couple’s feelings. Weddings are about celebrating the couple, not giving platforms to uncomfortable or attention-seeking behavior.

According to relationship expert Dr. John Gottman, “Repeated boundary violations, especially after clear communication, erode trust and intimacy. Protecting the sanctity of a marriage (and the wedding itself) is not selfish — it’s necessary.” (Source: his work on boundaries and conflict in relationships.)

The woman handled it maturely by addressing the issue privately multiple times before taking action. The friend’s refusal to stop suggests she values attention over the friendship. Mutual friends choosing sides is unfortunate, but the woman’s decision to protect her wedding day is reasonable. She should focus on surrounding herself with supportive people who celebrate her happiness.

This story shows how jealousy and insecurity can poison even lifelong friendships. The friend’s repeated “jokes” about dating the fiancé first crossed into disrespectful territory, especially after being asked to stop. Uninviting her was a painful but necessary boundary to protect the wedding’s joy and the couple’s happiness.

The friend’s refusal to respect that boundary speaks volumes about her priorities. Mutual friends choosing sides is unfortunate, but the woman’s decision was justified. What do you think? Was uninviting her too harsh, or was it the right call? Have you ever had to set boundaries with a longtime friend over jealousy? Share your thoughts below!
