It's been nearly 4 years for me. I swear I am a totally different person - more confident, FAR more assertive, I have interests that don't revolve around babies or TV (okay I still love TV but I like MY TV, not some somebody else has chosen!). I am a teacher now, something I never thought I would really do, I am moving abroad(!!!!!) in 3 weeks which is amazing and so exciting. I feel confident in my own appearance because I got glasses that I like, and a haircut which I love - it's much shorter than XP would have approved of.
Despite struggling with DS on my own I am now with somebody who makes me feel strong and like we could raise a small army of children together. He has pushed me and supported me through everything, work, study, parenting. He loves DS like his own, and he makes me proud with the wonderful things he does for us, and for himself.
I have been on holidays on my own and trips down to London on my own - amazing feeling to just arrange the childcare and go, not have to ask permission, explain where I'm going or justify anything at all.
XP 4 years down the line looks old and tired, his life seems to be getting more and more awful by the day and occasionally a friend and I nose on his facebook profile and laugh at him
He hasn't bothered to see DS in 2 years now and when he heard we were moving abroad decided he wants nothing more to do with him. His loss.
I said to DP recently that he probably wouldn't have been attracted to the person I was when I was with XP and I think it's true - so all of those people holding on because they are afraid of never finding anything better, well, you definitely won't find it holed up in that relationship.
I am also far less tolerant of other people's bad relationships and really have to check myself
when my cousin was upset recently following an argument with her bf I came very close to saying LTB and when she got defensive I had to backtrack and say I'm sorry, I'm being unfair. He isn't that bad. And it's true, he's an alright guy, he isn't that bad. But "not that bad" isn't good enough for me any more. I would, genuinely, rather be alone - the freedom is soooo worth it! And with a proper, healthy relationship you get that freedom, in fact, more than freedom, enthusiasm for the things you want to do rather than criticism and "concern" constantly.
