Hi
I know just how you feel. I got tired of being responsible
for the adult who was meant to be my equal, I too am emotionally buggered
and was just on the edge of worrying if I was a bad person, feeling bitter
and angry.
I tried to be grown up in the first instance by
suggesting that we seperate and start over, by falling in love again, but
he is an all or nothing bloke, and then what does he say when it is all
over, too much water under the bridge and too late....."how could I do this
to our boys, all the things they will miss out on, single parent" etc etc.
And I think he really believes what he says

, that he has done nothing wrong, which would
explain why he could never put anything right. He has had opportunity
after opportunity to try and put some of his wrongdoings right, instead he
chose to be dramatic, sitting and wallowing in self-pity, very attractive
... not!
Now he tries to make me feel bad for trying to get
off the roller coaster and attempting to find a good life before it is too
late.
Hope your stbx sees the truth at some point!
All the best
