Bema, I think others are hitting on something important here. That you may not be being honest with yourself about your motivations here. We see this a lot with LBSs, that they will convince themselves of something to justify actions that maybe you shouldn't be engaging. Begging, pleading, reasoning, pushing, etc. for almost any reason is the wrong approach. You broached the 2 day intensive with her. She said no. Now you are reasoning and explaining to her why you want her to attend, and in doing so I think you might be changing that motivation to fit a narrative.
Bema, some of the best early advice I received was to take the focus and your attention off of her and put it onto. I honestly believe that is at the heart of MWD's It Takes One To Tango approach. You cannot control her. You shouldn't even try. So, focus on you and your actions and make that where your energy goes. GAL, self-improvements, detachment that is your focus and it all deals with you and how you a behave and leave her alone to make her own decisions.
Bema, you haven't shared much of your situation with us. Most of us started with a post about our situation giving the history involved. You've done that a bit, but I'd like to see you post an introductory post giving us a bit more detail. I will leave that up to you if you feel comfortable doing that or not.
