KellyV,
I don't know how old you are or what kind of life experience you bring to this, but (speaking as one whose "been through it") you display an incredible level of matter-of-fact acceptance, maturity, and love that really is a quantum leap above what most ever achieve. As almost an aside, I can't imagine why he'd ever argue with you about ANYTHING! That'd solve the problem! If you guys don't make it, it's not on you! If he loses you, he'll regret it for the rest
of his life.
I'm not one who blames SO's for not accepting, even though that lack of acceptance cost me a 30 year marriage, and the love of my life. We ask for, and maybe even expect, to not be judged too harshly for being wired a little differently. The flip side of that is that we shouldn't be too quick to blame our SO's if they're not wired to accept it.
You are truly a gem. I suspect that this matter-of-fact attitude carries over into all other aspects of your life. It's really wonderful! Give yourself a pat on the back. Maybe you've picked up some valuable insight from this thread, but don't let it complicate your simple outlook. I love it!
