"Anyone who tries being in your life you shut out and ignore"?

How do I fix this, I dont try to shut people out ( okay.. maaaayybeee alittle) But I definitely dont want to keep living my life this way. I'd like to have close friends and not aquaintences, I'd like to have and WANT a relationship and not stuck in First date limbo. I really want to fix this... I just dont know how.
