Here is a support group page from the website of the Brain Injury Association of New York State. Your situation and that of your boyfriend sounds very complicated. Perhaps you could try finding a support group in your area where you may be able to get some ideas to sort out the situation. He may not be interested in it at all, but you need some support right now and that's what they're there for really.
