Gotan, I'm at a similar juncture in my sitch. I'm determined to turn this pain and confusion into progress and change.
Don't ask her to stay. She needs this from you as hard as it is. It seems contrary to everything you believe but this time she is away is good for you. Use it! Don't waste this pain. You are rocking things right now, just back off from showing her she's needed. Show her your changes by letting them radiate from within you. Don't talk R. Let her make that move. Keep working out and cross fit is a great way to get this stress out! PR in something tomorrow! You got this!
I find that being patient is turning out to be the hardest part of this journey. The self exploration, the work? Bring it! It's about time I did this kind of introspective work for me let alone for my relationships but patience? Man, that's a toughie! I'm trying to do a 180 on myself and look at this time as opportunity for more change, more time to make my emotional case to myself.
