It takes two people to work at marriage so it can't be totally your fault. Please don't feel as if you are the only one responsible to make your marriage work.

Have you tried marriage therapy? I heard it can help.

If you still want to salvage your marriage, please don't give up on him. He may turn around eventually so be patient and think of options to save your marriage, rather than giving up on it.

I hope others can chime in and tell you some useful advice also.

Best wishes and hang in there!
