You're not useless. You are still young. You wont end up finding the right guy, your first time. I'm still single too, ya'know. You really have to see down and ask him whats going on. 'Cause at frist I thought he lost a dare, but you need to talk to him, and if he does have someone else, you must leave him, or be ready to be left. "Actually listen." That sounds like a plan, you should tell him, but not leave it at that. Talk to him, and if need be get someone to (or you) stalk him to find out. Believe it or not, but in the movies where the private dic, follows someone around to see if he is cheating, really does happen. You may of already lost him and do even know. You need find out the truth.
