ExH and I have been divorced for 3 nearly 4 years. We have 3 DCs aged 3.5, 5 and 9. We split on mutual grounds. We both got to the stage where we realised we no longer loved each other and it just wasn't working. We get on fine now, we're not "best friends" but we don't hate each other. He's a wonderful dad and has a fab relationship with the DCs. Anyway, 2 years ago he got together with our old neighbour who lived across the road from us when we lived together. Get on well with her also, she's very pleasant and is fantastic with the DCs too. She's well off so olans great days out for the kids which I am very happy with. They have a 9mo together now and are getting married this summer. Annnywaaay, today, much to my surprise I received an invite to their wedding. Not just the reception but the whole damn day. Now despite having a good relationship with my ExH I wouldn't consider myself a close friend and whilst I have absolutely no feelings for the bloke anymore, I just find it so odd that they would invite me? I get that they want our DCs to be there which is fine - I have already made arrangements for them to get there & back etc. I just feel so weird about going myself?! AIBU to not want to go..... I really don't want to damage a good relationship with the father of my kids which is what I'm at risk of doing if I say no! Ugh I'm so stuck, I seriously don not want to go to this wedding.
