So this is the story, Lucy, Alice and I are mutual friends. Lucy and Alice were really close but then had a falling out, I can't even remember what it was about, but basically, the relationship broke down and Lucy no longer talks to Alice.
I got married a couple of weeks ago and both were invited to the whole day. I knew it was an issue so before I did the seating plan I told Lucy I wouldn't put her and Alice on the same table. Lucy told me not to be silly that she knew her and Alice could be civil for the day and as they would be seated with lots of other mutural friends it wouldn’t be a problem.
Yay I thought, I'll put the on the same table, not next to each other but I thought it would all be fine as they were sitting with mutual friends. Day was lovely, all wonderful. Then I met up with Lucy a week later for the dinner, during the meal she told me in great glee all about how she had spent the reception blanking Alice, ignoring her when she tried to talk to her, making a show of moving the centrepiece so she didn't have to look at her. Even how Alice tried to talk to her in the bathroom to clear the air but she just ran past her.
I didn't say anything at the time, but I’m so upset about it now as I feel Lucy has ruined my wedding day for one of my guests. I would never have put them on the same table if Lucy hadn't insisted it wouldn't be an issue. I spoke to Alice, she told me she would never have said anything to me but as I asked she had found Lucy's behaviour really hurtful and she had just wanted to clear the air so they could all have a good time.
I really don't know what to do, to be honest I feel like just pulling away from Lucy and quietly finishing our friendship as I think confronting her will make her go off the deep end, I’m just so disgusted with her behaviour and every time she talks to me I feel resentful. AIBU?
