If your point of view is how it was then that was an unhealthy and unequal relationship. Of course it hurts, but you did the right thing and you will be happier in the long run.

I've learned for myself to evaluate things as honestly for myself as possible. If she is any way right, I will immediately apologise and end the fight. But if I feel I'm right I will say how it is, even if it is hard to express and not give in. I will not escalate beyond necessary, but never give in. I will reevaluate arguments she gives, but only when I'm alone and at ease. I'm willing to deescalate, without giving in. This works for me (now).

If she does not contribute on an somewhat equivalent level to the relationship in your own measure...run. Relationships should be mutually beneficial. Don't let others take advantage of you.
