So I've been dating an amazing guy for almost four months. four months this Tuesday actually. I love him, and he says he loves me, but the past couple weeks it's seemed like he doesn't love me. He doesn't pick up his phone when I call, and is never online anymore, we haven't hung out in two weeks and I haven't spoken to him outside of school in almost as long. I think he doesn't love me anymore, and that he's gonna break up with me. What can I do to change things?
