Help me please!!!

So my boyfriend and I have been together for 14 months. He’s deployed right now and it’s making our relationship hard. I love him and I tell him that. The only problem is he doesn’t love me. And whenever I ask him why not, he says he just doesn’t. He’s been through some shit in the past, and honestly I think he’s given up on love. But I still do everything I can. I try to be supportive and make sure that he’s happy. He doesn’t talk about his feeling and when he does it’s not much. And idk. I don’t wanna waste my time if his feelings can’t match mine. But on the other hand, I love the fuck out of that man and I don’t want anyone else but him. What should I do?
