In other threads you speak about your childhood. I wonder if your childhood is affecting the possibility of having a relationship.

When someone seems to want attachment with you, you could be reminded that close relationships bring pain. Both your mother and your father taught you that. And by seeking those who are unavailable, you perhaps protect yourself from what your childhood taught you to be inevitable: great pain in connection with attachments.

You said in another thread of yours that you gained a lot from therapy. I wonder if you had the chance in therapy to discuss what you posted here.
