I don't have the guts to breakup with my boyfriend
I am not sure I understand. Why do you need guts to do that?
It's the fear of rejection and the fear of losing someone
You're breaking up with him, so he can't reject you. You're losing someone because it's better than the alternative.
What if I tell him I'm no longer interested and I want him to breakup with me.
You are making this very complicated but at the end of the day you are expected to find a relationship that makes you happy.
