I think im in love with my best friend?

alright, this happened to me before. you feel like your so in love then you go out with him but 1 problem once you go out, you feel it aint right and you dont wanna do it no more bc it is weird for both of you.and then you are stuck and dont know what to do...........that might of sounded dumb but oh well.... do what you think is rite good luck!
