All you can really do is be there for him, but you have to set boundaries too. For yourself. Then then enact those boundaries with him.

When you know you're being impulsive, stop and think for a moment. It helps. I do the same thing sometimes.

As for your boyfriend, hopefully this stuff can help. I actually posted this list for another user, and I hope it helps you too. Sometimes researching the diagnosis can give you a better understanding as to what to expect, or at least how to deal.

In the meantime, I would suggest some therapy for yourself. You're dealing with a lot, and now are under a tremendous amount of pressure feeling like you have to care for him. What you need to realize that dealing with his illness and your issues doesn't mean you need sacrifice yourself. You need to work on you a little, so you can handle yourself and then handle him without enabling him.

You came to the right place looking for support. We're here! I hope this helps. And I hope you help yourself too. You seem very caring, but always remember that caring doesn't mean you have to take care of everything BUT you. We tend to lose ourselves when someone else is having a crisis.

Take care!
