Beginning a new relationship.

I had actually given up on finding another person that can put up with me, I have Schizioaffective disorder and Borderline Personality Disorder.

Now, I originally I was just looking for a friend with benefits (That has been hit or miss, no one quite understood what I was looking for.) Anyways, I meet a guy with the same exact disorders I have. We felt immediately comfortable with each other and like each other a lot. I really don't know what to expect to happen here. Any advice?
