If you decide to stay I would suggest reading the 5 languages of love, it is a great book and seems to be a successful formula for many. The kicker is that both parties need to buy into it.

If your relationship is truly at a place where you have no respect for each other it might be time to seek the advise of a divorce attorney.

My wife and I are going through roughly the same issues, we are in marriage counseling. Some days it seems to be working, most it just seems like a place to go have refereed arguments.

One thing that our counselor suggested was a trial separation, with rules. No dating etc... really work on yourself. That is if you both want to make it work. It is abnormally tough dealing with these issues with a mental illness, as I am sure it is tough being partnered to somebody with a mental illness.

Best of luck to you, feel free to reach out and vent. that is what is so great about this forum. There is lots of great wisdom among the members here.
