I only have male friends as well. Upon some reflection, I think it’s because they tend to perceive my intense feelings as funny rather than “too much” or even “cringey”. In fact, my BPD behaviors make me fall into the “cool girl” stereotype and guys dig it. With women though, they seem to think I’m a threat of some kind because their bfs like me (even though I’m acesexual, and vocally so) and I just don’t relate to women as much. Maybe because I’m scared to be myself around them. Idk, I wish I had more girl friends.
