I don't know if I want this relationship or not. Please help; See details.?

Yes you do want to be with this guy obviously because you love him and your afraid to lose him. but the problem your facing is not with him but within yourself. your afraid to commit because you afraid that you will always have the fear of losing him. but in life you have to take risks. your going to eventually lose him anway if you dont commit. so if you dont even try to make it work you will be unhappy no matter what. but you still have a chance to be happy if you do.
