No if someone doesn't want you it's not your fault. It doesn't mean there's something inherently wrong with you. I had mentioned to my landlord (male) I'm female, that I give up and all I want is someone who can accept my faults. He put it in a better light. It's not about my faults, more about focusing on what I want and figure that out before trying to find someone. Then compromise is very important in a relationship. I don't think you did the wrong thing because you clearly wanted more than friendship.
