Yep, therapy.

And yes, good points, you are able to get boyfriends & you are aware that you are treating them wrong. Those are two good points, the second excellent as if you go to therapy you can at least admit what you are doing wrong and that's the first step. You just gotta figure out why you are doing it.

I would also advise to stop dating until you sort yourself out. It's very unfair to go around hurting people and I think you should stop this until you are ready to treat people with respect. It's not nice to mess with matters of the heart. Sorry if that sounds blunt, but it's the truth.

Hugs.
