Posting here as not really sure where else to post...bit of a back story. I was with my ex for almost six years - we travelled, went to gigs, lived a great life really. Although there were problems but I suppose at the time I was blinded by love. We planned our daughter and were overjoyed when I got pregnant. However, when I was 7 months pregnant he said he didn't think he loved me anymore. We remained close and he came to the baby shower and birth and was very hands on at first. We got back together when she was a few weeks old but he became distant and when she was four months old he ended it. Days later I discovered he had met someone new. There relationship moved really quickly and they were living together within weeks (with her daughter). They got engaged last September (after 8 months) but then split in February. He was threatening suicide and turned to me and my mum at the time. However, within weeks they were back together and had planned their wedding. They get married on Sat and it has thrown up so many different emotions for me. I know we wouldn't have lasted long-term and up until now I did feel like I had moved on and was over it but I just feel so weird about it all. We co-parent quite well despite what happened. He usually has our daughter for 24 hours each weekend but will ask to have her more when he can. He has her for three days this weekend for the wedding and it's the longest she has ever been away from me. She's just turned 2 and is still bf. I've got plans on Saturday to go to a festival with a friend but I have been hit by an overwhelming feeling of sadness tonight - I'm not sure whether it's the thought of being away from my daughter for so long or the fact they're getting married. His new partner has been nothing but vile to be since day 1 and my daughter is staying with her the eve of the wedding despite me raising objections to this (she doesn't settle well and I'm worried how his new partner will deal with this the night before her wedding). She's then staying with his mum the night of the wedding - again something completely new for her as she has never stayed with her before. I don't know why I feel like this. I've not moved on and met anyone else as I just haven't felt ready - nor do I have the time as between working full-time and having my daughter there is very little free time. I moved back in with my parents to save for a house and I just feel a bit stuck while he seems happy and has moved on with his life. Any advice?
