And one more aside, as I know I'm taking up too much of a thread not dedicated to this, but I'm not a player or ever cheated on a woman. I'm just saying that when you're dealing with a borderline, that is going to force a strong codependency relationship, the advice is you're going to need another person when they do those raging cold spells to maintain your own value.
Your collective self value is very important to maintaining a borderline relationship. She must always feel your worth is higher, or she will abandon you first. Their main fear is abandonment, and they're already abused people that are also prone to abuse. I don't advocate treating someone who perpetually feels like shyt worse, just for sex. They have a pretty high suicide rate, and when you get into their history, you see why.
It's just you need to find your own comfort, because they're the most emotionally draining people, and the most motivated when your worth level stays higher, that you can meet.
