Breaking up

I really wish I wasn't with my boyfriend because he barely pays attention to me and I don't feel loved. He swears he loves me and when we're together is amazing but I just don't feel love for some things he did before. Sometimes I attempt to break up with him and he acts strong and doesn't say anything for me to stay with him, and that makes me really really sad and I think I'm too attached to him to let him go. Idk what to do
