I've lost quite a few opportunities over the last few months, because every time a girl I'm attracted to shows interest, I try to get away from her. I shut down the chemistry from my end and avoid interaction.

It's worth mentioning I got out of a painful LTR earlier this year(I broke up with her if that is important)...this was my first and only. I'm not good at escalating chemistry to the physical level, probably due to a lack of experience. Most likely I'm scared of being rejected and hurt again, so I avoid girls when they give the green light...how do I stop doing this?
