Hops, in a not completely understood yet way, this is an evolution for me; a "levelling up" may be a clearer idea of how I used to interact in relationships. Hol & I briefly discussed the phenomenon where usually the female gives up part of her life/self in exchange for the relationship... entering into the male's world/worldview and forsaking her own. She called it pre-codependent. It IS a thing I've done in the past - it's beyond chameleonism - and it's always ended up non-reciprocal years later; as there is no invitation or expectation for the partner to enter MY WORLD, as well.
Well, partly due to the long wait and distance, I had to do something different. Earlier, maybe last year, I would stagnate into inaction and impotent mopey emotional states... and it felt familiar; just like those early days of grieving Mike when I simply couldn't move out of the "wishing him back" feelings. Obviously that's impossible. And it's just as impossible to wish B here, sooner than he can get here. So I decided to try to just live my life as I was pre-Buck; and still maintain close communication/feeling connected with him. And it's not just one way; he's doing the same.
When he's here; he's here and we can explore other aspects of our connection. But when he's not here - as he's winding things up - I have things to do to have the house ready to share; and work to do on the farm, to keep the project moving along to the point where maybe I'll make it official with the county (probably be another 3 years before that happens) and change the designation of the property, change the tax status, etc bureaucracy/business side of this. Our relationship doesn't include me "needing" him to share the work - altho this seems to be his natural bent.
And doing both things - maintaining a relationship while I move forward in my own life - is opening up the idea that this is a healthier way to relate; more to my liking for sure; and I have no idea where I got the idea that it was a requirement of a relationship to give up that much of myself in the fusing of a "we"**. Definitely losing that idea and watching myself for the reflex; stopping it when I notice it. I ain't doing that again. It's not NECESSARY; it's something "extra" that almost always breeds later resentment while forging that "we" space. It is reassuring that any time I make noises about being that way - B reminds me he wants an equal, with her own mind, life and ways of doing things... not a moldable robot that he can program any way he wants.
** Yeah, it sounds like enmeshment but I think it's a little more convoluted than that. And definitely more subtle. But whatever...
At this point, having worked so hard to get "me" put back together & functional after Mike, to understand who I am now - coz I'm not the same woman Mike married even; to say nothing of who I was before that... and to get back into the "decision>action>adapt & repeat" mode. I don't plan on giving that up again for anyone/anything. I'm standing up in the middle of my power; B is coming "correct"; and he wants to be part of my world and I'm giving him room and time and the space to reinvent his too. This doesn't intimidate him; doesn't scare him off; he likes it.
We have no commitment that this will be forever - except the emotional one; that we WANT to be together with plenty of space for us both to be who we are. He is intentionally giving up his world - that was his plan after his D got settled in college anyway; before sparks flew - only he was looking at inventing a new life all by himself. Then I butted in, with all my ideas.

We work well together. The chemistry is of course intense, when he's here. And we're able to talk to each other comfortably about most things; he doesn't like revisiting his painful divorces or talking about what he did on active duty; what was expected of him. He DOES... because he wants me know; he doesn't want to hide things - and he wants to know I'll accept those things about him. I do. And he's working very hard to make sure all that slides into his past... and stays there. He wants to live differently, and I can offer him what he had growing up in the mountains/woods. I do remind him a lot - we need to imagine some fun things to do too; not just work. He knows my story, too.
We respect each other - for what we've done in life previous to this; and who we've become as a result. We trust each other - and are still at the stage we're still actively working on this. I will say that I trust him more now; before he's even here than I thought I would. Neither of us are fans of playing the games that go on between couples. So I think we've got a fair chance of this working out.
