I hope therapy is helpful. You can only control yourself and what you're willing to change. I wonder if re-employing some of the DB strategies would be helpful, whether your current relationship works out or not. Spend some time practicing GAL and caring for yourself if you're not already doing so. At a time when you need to be at your best, it is important to eat well, sleep, get some family or friend time in, etc. so you have some balance to the negative stuff happening with your partner. Even though MWD says one person can make a significant impact on a relationship, in the end, the other person has to choose whether or not the change impacts them enough to salvage the relationship (to Cadet's point). Do the best with what you can control and, hopefully, you feel better however the relationship goes because you know you did all you could with what you could.
