Well, just try and understand that right now she is DONE and she has NO ATTRACTION to you AT ALL. She doesn't like you and may even hate you. Everything you do to try and get her back repulses her. She is thinking "why couldn't he do this when I asked him to, instead of waiting until now when it's too late??" There's a lot of anger and resentment there. Nothing you do is going to help, but there's a lot you can do that will hurt your sitch. ESPECIALLY pursuing. Believe me we hear that a lot- "I have to pursue her because I distanced during the M" but no, that is not a 180 that she welcomes right now. Her feelings will change over time, but she's going to feel this way for as long as you keep pursuing. If you can pull back, stop the pursuit, leave her alone and work on yourself then eventually she may see you in a better light. ... "I love you and think you're making a mistake but if you feel you have to do this I won't stand in your way".
Yeah it's called opening the cage door. Right now she feels trapped by you and feels the only way out is separation and divorce. If you let her know you're not going to interfere (and you quit all the pursuit behavior) it'll take the pressure off of her and she may not feel it's so urgent after all.
