Maybe this will take some thought on your part to determine which relationships that you need to pursue and nurture? Maybe something to discuss with your therapist? (And discuss here too if you want).

This was an issue that I really had to work on. I had closed myself off to intimate relationships and I had to work on it to figure out what I needed to untangle so that I was able to let others close to me. And I figured out all of the things that I did subconsciously to keep others away from me. When we think that it is the others who are in control of why we don't have close relationships, really, with a closer look, we are doing things to keep others back.
