What if my boyfriend doesn't believe me? I'm really falling apart. He is suspicious all day, which makes me feel very tired.

Why don't you think about it the other way around? He loves you very much. You should talk to him face to face. You can tell him that you can trust me. If you don't believe me, let's break up, but it's best not to say goodbye, because such a boy will love him wholeheartedly if he loves someone. You said that breaking up might make him do something exciting. And don't always say hello. Everyone can't stand it if you say that every day. You just lack communication. Just talk more.
