I know I am and I knew I would find this out eventually but it's still made me feel a bit "ugh".
I was browsing Facebook (i know, I know) and saw pictures of the two of them except, annoyingly, she has set her FB to private 
I don't feel as bad as I thought I would but it's like seeing another person, not the guy I was/am married to (still to get divorced). And now it's like she's stepped into my old life, in my old house with my old friends.
I left him so I really shouldn't be thinking about it but we were together a long long time and it's just sad how we were once so happy and now it's over and we've both moved on. I'm in a new relationship too and we have a baby together and we're happy but my exH and I did at one time think we would spend the rest of our lives together but it didn't work out like that. I can't talk to anyone in RL about it because they were all devastated and shocked when we split and they'd probably say I told you so. It's not that I want to be with him anymore it's just that he's now with someone else which is strange! I've always wanted him to be happy and I hope he is. People have mentioned how going through with the actual divorce is hard even of its what you want and I couldn't understand it but I think now I can see what they mean. Maybe I should get on with that asap to get it over and done with!
I hope this doesn't come across as self pitying twaddle although I am feeling sorry for myself for some strange reason!
