Why does someone get into two abusive relationships in a row? Probably because they grew up in a household where abuse was normalized and they don't have the normal radar to avoid those guys. (Look, I suppose it could happen to anyone once, but twice implies some issues).
And this sometimes means that a normal relationship without drama is not attractive to them. She probably has issues she should be working through with therapy. Probably best for you to just stay in the friend zone and focus your dating efforts elsewhere. Don't try to be the white knight.
