Yeah like the other guest said. Asking about it is the only way to find out. Neither of you can read each others mind. He could be shy or he could be having personal problems or maybe he's lost interest in you. Whatever it is he needs to tell you, but he's not, so you have to ask. Let him know you're concerned. He doesnt seem responsive and that isnt fair to you. Let us know how it goes please! (Also the other person talking about fucking, uhh. You dont owe ur boyfriend that lol thats not what a relationship is about. Also thats an incredibly inappropriate & shallow thing to even say.)
