I used to have this problem until it pissed a girl off that I really liked which hurt me a lot when she more or less kicked me out of her life and blocked my number for "blowing up" her phone.

Now, I do the opposite. I text or message people so rarely that people think I'm not interested in them. I text only to reply when somebody calls me and I never call unless it's urgent.

The fear of being hurt again overtakes my desire to talk to people I guess or perhaps I'm just bad with people?

Sorry I couldn't be more help but at least you're not alone.
