What do i do if i love him but don't want to be with him?

If you love someone the you should want to be with them and I have no idea why you are trying not to love him. Doesn't make sense to me. Unless he's into drugs, alcohol, a jerk or an abuser, or married then it appears you have found a real nice guy. You need to ask yourself what is stopping you! Good luck Merry Christmas Marcy
