I think the OP is asking honest legitimate questions and it's better he be honest and ask them now than to wait until he committed to this person. I have BiPolar (according to doctors) and my illness could scare off anyone. My husband didn't know I had bipolar when we married but he did know about all issues I was aware of and how they effected me. Not everyone with bipolar is a burden to everyone....but to some people we would be and its rather brave for the OP to admit he has these concerns.
