My question is how can I start a relationship with her again, even one just talking, if she won't let me in?
First of all, you'll get more replies to this in newcomers.
Second of all, in answer to the above question, you can't. She doesn't want a relationship with you and you calling her is, "not getting the point". Maybe it would be easier if you envisioned her grimacing in disgust when she sees it's your number or makes a joke about you with her friends when you hang up. I've seen it. You are divorced. Any attempt to form any kind of relationship right now, when she doesn't want one, is completely transparent and a major turnoff.
What should you do then? Start working on making yourself happy and complete without her. Get comfortable in your own skin. Do things you enjoy. Take up new or old hobbies. Enjoy your life. And eventually, when you are ready, invite women back into your life. And don't bother with her for now. Put her on the backburner. The decision to ever try again is entirely hers at this point and to put your life on hold, waiting for that decision, or worse yet, trying to get her to make a decision, is wasting your life away. The goal is to be happy either way. Hey, she isn't all that (and a bag of chips)...she essentially ran off on you when you were at a difficult point in your life. She had no real sense of committment and probably is a cheater besides. Get happy with your own life and if she does take an interest, you can decide then whether she actually has anything to add to what, by then, will be an excellent life. You might surprise yourself by answering that she doesn't have much to offer (except something you can't have).
