he doesnt want the feeling of failure
I`ve done some research on this and it could be for a number of different reasons.
He's comfortable with her and doesn't want that comfort to end.
There are kids involved and staying with her because of them.
He could be in denial and thinks things will change for the better.
He could be financially trapped and has no way out.
Religious or cultural reasons.
Afraid of feeling shame if he leaves her.
Fear of feeling like a failure.
He may see the fighting they do each day as normal. Some do when they`re raised in families where this is what happens daily.
There is no such woman.
That is the 'turn on' if you will?! Some folks actually like the strife!!!
Failure. Men don't like to fail.
I would say it is less about the abilities of the woman and more down to issues that the dude has
