my DP and I are in the middle of an almighty row, which has escalated and is threatening to end our relationship. without going into all the details because it will take too long, we had made a decision, I thought jointly, not to go to a colleague/friend of his wedding which is in a few weeks. we have discussed this lots of times, and he has always maintained he is not bothered about going. the invitations came out, and nothing changed with our decision. he then spoke to the groom about if because he wanted to be upfront about it. the groom was apparently very disappointed. now, my DP is a total people pleaser, he cannot and I mean CANNOT make decisions if he feels he will let someone (other than me) down.
then on Monday, the groom emailed him saying how disappointed he was, how my DPs reasons were not good enough, and saying that just because I don't want to go, my DP should have the freedom to do what he wants, and lots of other really snide comments about my DP doing what is 'right'. it was a total manipulative guilt trip. my DP sent it on to me, which I really wished he hadn't. I barely know this guy, have met him twice for approx 10 mins each time. anyway, you've guessed it, my DP has done a U turn and is now going, without me. he won't listen to anything I have to say, he just says the goalposts have moved.
I feel completely betrayed by him, not just him changing his mind, but also not sticking up for me over the email. the reasons we weren't going to the wedding relate to an ex of his who will be there and i am just not comfortable with this. my DP doesn't care, he's going and that's that. sod all our joint decisions, sod his promises to me, none of them matter now as he doesn't want to let this guy down. so I've told him I can't be with someone who just disregards my feelings like this and now we're on the verge of splitting.
the saddest thing is we were supposed to be moving in together and were both really excited about it. it's all been ruined now.
can anyone give me any advice on what to do? im always the proactive one in our relationship and I really don't want to just make it all better this time. he's hurt me too much.
