I think I can relate. I am also BP2. I left my husband 6 months ago. I was diagnosed afterward. Its hard to imagine finding someone who would understand. But I know those people are out there. Your boyfriend probably has no idea when to reach out to you and when to give you space. Ask him how much he wants to know and try to get a sense of what he's comfortable with. You know how much you can handle on your own and what you need help with. I bet you can get what you need, but it's scary to ask. You're right, you just don't know until you try.

After feeling rejected after 30 years of marriage, it's hard to have a relationship where you're not scared you'll be rejected again. But if you don't find out early in a relationship, you might find out later and that would be worse.
