I second Pup and agree with Gucci, especially about the critical spirit thing. I'm going to guess that's one of the reasons (probably pretty high on the list) of why she has for the most part shut off contact with you.
Getting intentional about NOT being at the gym while she is there is an excellent idea. In many ways, she STILL feels suffocated by you. Remember her birthday where you put flowers everywhere she breathed air? You said you learned your lesson...you need to prove that. Not being at the gym while she is there is another step in that direction.
One of the things I (and others) pointed out to you a long time ago was that your e-mails had WAY too many questions in them. Questioning everything and wanting things done your way is a sign of a critical spirit.
Take Gary Smalley & John Trent's personality test if you haven't already. Once you've done that, you can get some insight on both your positive and negative personality characteristics. Continue to strengthen the positive ones and think about how you can lessen the negative ones. This is something I am doing now as part of my own growth process.
