p.s. TLV, Dior is right. I definitely didn't have the strength at first. And still don't some days!
I always had the strength to fight for the relationship, but sometimes felt so low trying to win that battle, that even getting through the day was a struggle. Didn't have the strength for me iyswim - just felt like everything was pointless without H and the key to my happiness was getting him back.
It's the fact that they take away your confidence and make you believe that it is somehow your fault. As though you weren't good enough and that's why the relationship is over.
Takes a while, but you do realise eventually that the problem is generally with them. Because they are too weak/selfish to deal with issues like a grown up, and prefer to just bail out or find another woman. They conveniently forget that they once made you a promise 'for better, for worse'...
Attention from other blokes and being treated well by men was what did help me to realise that I deserved better. Doesn't make it hurt any less though. You just numb the pain by taking your mind off it. It's only time that really heals. (And counselling in my case!)
Like I say, I probably have a lot of buried anger and resentment inside. But all you can do is take one day at a time and deal with it in whatever way gets you through.
We're always here to listen.
