Lovely to hear from you all and I've obviously hit a nerve with not just me. I guess my situation is slightly different in that I knew the relationship was probably over, but I was willing to make a change and carry on for the wrong reasons (ie, comfort, family, outward appearances). I actually prefer not being with him and I'm absolutely fine, just me and the DC. Although he behaved like a tw*t and moved in with OW and her children straight away (barely even stopped at traffic lights!), he has been reasonable in that he has said he's happy for DC not to meet OW or her children, and thats been 8 months. DC wouldn't go anyway, but the fact is that I'm grateful he's not pushing it.
I'm very lucky in that I have a brilliant friend set, and am always busy and actually enjoying certain aspects of the freedom, for example, not having to answer to anyone, not hearing "what time will you be back?", not having to check on plans when we're invited places or family gatherings. I can do whatever I bloody well like (within reason) and it's liberating. I have a very responsible, demanding job and my phones goes all times of the day and night - again, no one tutting in the background. My DC tag along and I rarely don't take him with me - he's my little friend and luckily he plays with all my friends children. Ex-OH see's him on the school run 3 days a week, takes him to football and occasionally has him one afternoon on a weekend. Not much, but then I don't want to push it or he will say "fine, but he comes to me". So, you can see I have a lot to be thankful for.
HOWEVER, I still find myself crumbling - not fighting back or saying what I really feel because I know it will p*ss him off. Do you know what I think it is with me? That hope that he's going home to "her" and thinking to himself "actually, ex wasn't that bad after all" and making OW look bad!!!!
It's simple - I don't want him, but its horrible NOT being wanted. Someone NOT wanting to be with me, spend time with me. Someone actually CHOOSING to be with someone else. Doing all the things we used to do.
And for that, I hate him. But still love him.
