I would agree that when it gets to that point where your sanity is at risk ,
then it’s time to walk away. If you have the means then you should go out
there and try and make a life for yourself. I think this holds true no matter who
it is. If it can’t be fixed then it’s broken. You can still try and have some kind
of relationship , but from a distance. And don’t let him try and lay a
guilt trip on you.
