Cognac, just read the other thread. I too wanted to stay with my ex - for the children. And because a broken marriage would make me a loser. These were not good reasons.
My life has improved steadily from that low. I'm still working, financially secure (not the case in the marriage), my children are happy and healthy adults. I'm in a good and balanced long-term relationship.
Best of all I've more self confidence than I ever had before!
Wish you all the best, just don't give him too much undeserved power.
