It's natural to feel sad. Anyone bp or not would feel sad and it's also natural to feel a bit scared that you won't find someone else. Sometimes a person can have a selective memory with relationships and only remember the good times. I have dated people that can trigger my bp and it just doesn't work, no matter how great the good times are. I can't be on a relationship roller coaster and I know what I need in a partner is someone that is calm, confident and happy. The whole drama thing I know doesn't work, yes the passion can be great, but you can't only have a relationship based on the sex life.
