These running shoes are wearing thin

I'm so sick of running - WHY? Seriously why? Why the moment a man treats me with such respect, such love, such a gentle touch and desire to take care of me, do I feel the need to take off? Why do I let myself get scared off? He takes me on a romantic date, trys to treat me to supper and dessert, asks me to dance by the pier, walks me to my car, asks for a kiss, holds my hand, tells me i'm beautiful, sends me sweet love texts. Why when a nice man like this comes along, asking me to come over so he can cook me dinner, why the hell am I feeling like now this isn't what i want. I can feel myself slowly slipping away and I don't know why. I mean I know that I don't want a relationship and I have made this clear to him - but why can't I just enjoy the time together, why do I keep finding myself making up excuses and getting scared off. He's so sweet and would take such care of me so why?
