I don't know what the offical DB-stance is on dealing with spouses that put their body parts through poor, defenseless, inanimate objects, but my stance is please be careful.
Maybe that is one line/limit that you should think about etching in stone??
I don't know yet because I haven't been put in that place, but to me in the situation I am in, physical injury is in a different category than the PA/EA stuff. I find myself accepting a lot of crap wrt to emotional 'abuse' (used loosely), but my own physical well being is sacred to me.
Actually, a LONG time ago, I told H that if he EVER dared to reach out and strike me, he'd be pullin back a stump... Seems a bit barbaric now, but I think he got the point
Please take care of yourself--nobody here wants to see you hurt like that!!!
