Damn 2step I really don't have anything to swing at. This conversation happened because it had too.

If you can at least look at this as a a do over. You do actually have the opportunity for a possible fresh start.

I think you just continue to not initiate contact. Let her come to you. Let her trust you. Let her feel safe talking to you. Allow her to figure her feelings out. Let her feel whatever she wants to feel. I actually hear what she's saying. Do I believe a 100% of it? No, but I'll give it 50%.

Again, let her come to you. She walked out, she has to walk back. Keep handling the calls with a calm approach. One thing you have to stop is the finger pointing. You said it, She knows it; any more talk about it is a pi$$ing contest. Move forward, don't revisit it until she does her work and actually tries to walk back into a relationship with you(If you choose to). Only then can you figure out what to do differently from the past. You are working on it already, she hasn't even begun.

I think she genuinely feels bad and she's angry. You have a long road ahead, but I think there is a strong chance she might come back with an apology and attempt something new. You have a great opportunity to really evaluate yourself and really figure out what you want. Tough choices ahead for you bud. Just keep stepping forward until a clearer picture appears.
