A simple question.

A girl in my friend group that I find myself attracted to. We have already hooked up and connected emotionally, but she came from a long term relationship and isn't looking for anything serious at the moment. How does one ignore or subside their feelings for someone? I've been trying but everything I learn or apply can't seem to ignore this feeling for her. I've tried dating other girls, flings with others, but it's not happening. What does one do?
