Re: why do i feel like the looser?
If the problem is his, and you are trying to help him, then you obviously have genuine feelingins for this guy.
Be kind to yourself, get reading about his condition, this way you'll have more knowldge and insight to not only him, but your role in helping him too.
Go to the library, read, read, read, . . . . . . ..
Then you'll know how to help him and look after yourself at the same time.
