i miss the feeling of being in a relationship

I'm bi but idk, ik i like girls but I'm unsure when it comes to men. I've only ever been in one relationship and that too was titleless. Maybe people dont approach me or I'm not the type to get liked. I'm not trying to be pick me but for some reason, I feel as if I need someone to like me to prove to myself that I'm loveable. I feel spoilt. I have a decent family and amazing friends whom I know love me a lot but I still feel unlovable. I'm so desperate for a relationship it's embarrassing.
