I feel that you can only express your feelings to him. Let him know that you want him, love him and don’t want to lose him. But, after saying that, he must make a decision. He can’t treat you badly. You didn’t do anything wrong. He loves you and is afraid of
losing you. But, that doesn’t mean he can hurt you like this. You have to talk to him again and let him know that it’s not you’re desicion to end it, but that he has to be in it as much as you are. If he isn’t strong enough to have the long distance relationship, then end the realationship for now. He may realize he’d rather have you in his life long distance than not at all.
