I have noticed a recurring issue with my dating life. I get a lot of interest from a girl then I cause all of that interest to be lost.

I think it comes down to my fear. I don't want to screw things up so I intentionally will not text them for days in between dates so I don't appear needy. But then other times I will seem to be the one who is too interested. It's as though I can't find that middle ground where they know I am interested but not needy.

My confidence isn't the absolute best but I am definitely capable of seducing girls; especially one night stands. But I don't really get that much pleasure out of one night stands; I like getting to know someone and developing a relationship. Most of my friends aren't like this so it's hard to really gauge what it is I am doing wrong.

For example, I dated a girl for about 5 weeks before she lost interest. I brought up what I sensed from her and she gave excuses that communicated to me a lack of interest on her part (can we just be friends? I'm not over ex, etc.). I have enough experience to know what those mean so I stopped communicating with her. I never heard from her after that, but she claims via mutual friends that I didn't seem interested... A month after she started dating someone else (already over the ex, huh?)Haha ok. So we were really into each other then it died out fast.

TLDR; basically, girls lose their interest in me after things seem to be going well. How can I improve so that this doesn't continue to happen?
