I want to finally break up with my boyfriend for good
Do you think breaking up with him will fix your problems?
When I try to break up with him there are always problems.
If you don't think there is a way to resolve the problems you have, it is good to talk to him so that  you can end the relationship cleanly. It will lead to less hurt feelings.
I'm doing this because I hate him. He's going to suffer so bad along with me.
But wasn't he someone you used to love very dearly, why would you want him to suffer? Don't you think it would be better to just talk things out and save the drama? Think of his side, he may still love you very much and wanting him to suffer could hurt too much.
