If you feel you want to share this information about yourself, I would support that. However, I strongly disagree that disclosing one's medical history and/or financial status is a "courtesy" that is "owed" to someone you have recently started dating. Be open, if you want to be open, about whatever you want to be open about. But do it because you want to, not because you feel there is some moral obligation to spill your guts. There isn't . . . not to someone you barely know. I don't care how much info you two have exchanged on-line, until you spend actual time in his presence, you do not know this guy. Ask yourself to start listing his faults and flaws. Can't think of any? Then there is a heck of a lot that you don't know about this man.

The fact that you say you are so nervous tells me that this is too soon, but go with what gives you peace of mind. The truth, IMHO, is that no one really knows what is or isn't a deal breaker, until they are confronted with the implications. People today seem to want a guarantee, or some way to foresee how things will go, before they even really get into a relationship. Life has taught me these two things: There's stuff I thought I could never put up with that I can tolerate or work with. And there are things I thought wouldn't bother me that I later found did bother me a lot and that I needed to get away from.
