MLC - do you act like your still married?

[yawmom]

I mean, husband is a truck driver - all signs point to MLC. He's not home and when he comes come me make love--I want to and don't expect him to say the words but lately he's more caring. He had an affair << hasn't seen her but didn't tell her it's over yet, so there's a concern.
I can tell he loves me, been together for 25 yrs. He's a good man who tells me he's all F** up in the head.
I don't really know how to act towards him. I did order 2 of the books, but want to know before they arrive what to do/say/expect.
Site is wonderful, gives hope.
Thanks so much!
