To Angelic Victory ...
From what you just said, I can see that trying to convince him into seeing a couples counselor (a prior suggestion of mine) would be a waste of time - and probably getting your hopes up without good reason. That was an incredibly hurtful thing for him to say or do to you!
And yes, I would agree with 'getting by' - that people say things they don't mean. Unfortunately, we do it too often in a relationship. But ... it is possible to stay with someone because it's a comfortable situation - and not love.
I was in a 7-year relationship that had 3 separate start and stops. Looking back at it the past couple of years, I'm convinced the last 2 starts (or re-starts) were because we were so comfortable with each other ... and I think that statement applied to both of us. The love had dissipated after the first break-up. And blinders were on from that point on.
Right now, he is obviously the opposite of any form of suffort for your other problems. I guess, if you can, keep peace until other things are under control - then ... what choice is there but to say good-bye! It's a destructive relationship that needs to stop - and it is his problem not getting over his former wife - not yours ... but, he can't separate that!
Prepare well .... and peace to you and your children
