I'm sorry, there's no way of telling what's going on with him.
Some of what you see may be attributed to bipolar, some is clearly not.
My advice: Hold the very same expectations you'd have of any guy you get involved with. No special breaks because he has said he lives with bipolar illness. What type of a man are you looking for? What type of behavior are you expecting/hoping for? Is he meeting your expectations?
Good luck to you while you search for a love that treats you right. No excuses.
