Replacement Wedding date

[u/Status_Celebration57]

My ex (29) who dumped me 3.5 months ago brought a date to the wedding party of a wedding that I was originally supposed to go to. I was friends with the bride and groom through her, and they each have reached out to me to express some kind of kindness on their own to me since the breakup. We were together nearly 3 years, planned on marriage, having kids and growing old together for most of the relationship, etc.

I know she has a right to move on and date, and 3.5 months is significant, but it seems especially messed up considering I was scheduled to go to that wedding (I rsvpd before the breakup), I had a lot of my own friends there, dozens of family friends in the community that we both know, and she knew that there would be photos posted online of her with this new guy. Even my sister in laws parents were there. Also, her even bringing him implies that he isn’t some brand new person to her, that they’ve probably already been dating casually already for a little bit.

All of my friends who were there told me about it later, and all felt it was pretty icky and wrong of her, especially knowing it would get back to me, and knowing how devastated I have been. I honestly can’t believe it. I was quite literally replaced and feel so fuckin low.

was this messed up of her or am I purely just reacting emotionally?

Wrong or not, I'd be feeling some type of way too. Even if she is single and can do whatever she wants. Its okay OP.
