I guess one other bit of info... I really do think I've been doing a far better job on myself, especially over the past couple months.
I've been working out and lost 15 lbs. I'm doing a lot of the manual labor around the house that I didn't before (replaced a garbage disposal this weekend! Before I never would have tried pulling that off).
Also, I haven't been obsessing over things (at least in a way that's visible to my wife). I still tell her I love her. But I don't force hugs or kisses.
I'm doing my best. Just feel like she's too far gone.
