<human>: Can you succinctly summarize the text in 1-3 sentences?

Hey Reddit,
     I'll keep this pretty short. I'm a 31 year old male that is so focused on my own faults that I am unable to date anyone. I am so worried that I will hurt someone (Emotionally. I am not an angry or violent person) or mess up her life somehow that I just can't let anyone get close to me. While I do occasionally go on dates (I do want to get past this somehow), I cannot bring myself to go beyond the first date, no matter how well it goes (this isn't recent. I've never been on a second date in my life). If the date does go well, I will either make an excuse to say no after that, or just not answer any calls or texts from her until she stops. I know that this actually turns me into what I fear, since this probably hurt some very kind women, but I still can't make myself progress to any type of actual relationship.  

What really makes this a problem is that I don't have any real reason to believe this. I don't have any deep problems (I don't drink, do drugs, gamble, or thrill-seek, mainly because I know I have an addictive personality). I'm a pretty average guy, I think. And I actually do well socially. But when it comes to dating, I can't seem to get past the thought of "If this becomes more than one date, something I do or say will hurt this woman."
  
Has anyone else ever felt like this? How on earth do you get past it?
