Why do women run from love ( the men who love them)?

I find myself going out with a guy, and really caring for him. He sweeps me of my feet, says all the right things, and touch me in all the right places. He takes my breath away and I am so content with what we have , then he goes and f--- things up when he gets all sensitive and s--- and what to tell me that he loves me. It seems that I lost all interest in intimatcy. This s--- seems to go in cycles. It is happening again and again and again and I keep running . What's wrong with me ? Most women would love to have this? Why don't I???????????
