My power being used for great and good things.

Instead of... well. Ok, this is technically still manipulation, but at least it gets something positive out of itself.
I'm definitely not over him. Won't be for awhile.
Probably never will be.
But being a cunt is the only way he'll stop hurting me.
The only way he'll stop lying.

Two things will possibly be the outcomes of this:
One, of course, would be him seeing me as a heartless bitch so he'll have no love interest in me anymore.
Two, my possible favorite and worst, he'll end up coming back to me because he sees me as different and unusual.

Option two happens a lot more than option one.

I love you. Forever.
I hate me. Forever.
