It sounds to me that you do like this fellow much and he does you in return. It also sounds though as if you are hurting very deeply over this past issue and you you are no doubt not ready to date. You need to work through this pain before pursuing a relationship. I suggest you do apologize and let him know that you have some things to work through, that you would like to remain in contact at least on FB, and that maybe things could work out in the future. In the mean time, YOU NEED TO GET HELP. This is not going away by itself. Find a therapist and work through this. I hope that helps you. I really want to be a help.
