And you wanting to walk away because he's withdrawing? Further, with regards to the type of support you're wanting - are you wanting help to prevent you from walking away?
I think I answered this in part, but it may not be clear.
I don't want to walk away at all. I want to love this man, for as long as I can.
I'm tending toward that option because I see his withdrawal as abusive, at times, through the filter of my past.
I want help in being an appropriate friend or girlfriend, to him, and one that can model healthy behavior to him. I don't think he's ever known anyone quite like me, as educated or as knowledgeable in relationships (as a partner I mean), nor someone as committed as I am, but we're both scared, and reacting. One of us needs to stop reacting. lol. It's gonna have to be me. So, that's what I need the most help with, and that's what the 180 would be for. Appropriate boundaries would need to feed into that.
