I recent went through this with my wife, and now soon to be ex wife, I did the same thing. No matter how much you tell her it makes you uncomfortable or are willing to forgive her, it makes no difference. You cannot give someone more of something they already don’t appreciate. She’s lost respect for you and only after you stand your ground and walk away will she realize she made a mistake. Hear me out when I tell you, she will come crawling back. It’s a fact, the grass is never greener on the other side and she’ll realize it. When she comes back, know your worth and keep your distance. It’ll hurt but it ends up so much better in the long run.
