HELP! Does he love me or is he using me?

I am sorry but he is FIRED!! It sounds like this guy is just going to end up hurting you. If you are already doubting the relationship then there is a problem. I would just go back to being friends with this guy. If he truly was in to you he would not be trying to get into your pants. Oh one more thing, do not lie to yourself and say deep down he has a lot of feeling and emotions. This guy is playing you and in the end you will be crying in your room alone while he has some other girl in his bed.
