You are just a cutie-patootie!!
Maybe getting up with your husband and making him a special breakfast before he has to go out there and face the day. (Omlet, pancakes.. maybe just eggs and toast?)
Put a note in his steering wheel that you love him and are proud of the way he provides for your family everyday.
After the kids are in bed, give him a back or foot massage (whichever he might enjoy).
Maybe do one of "his" chores that has been stacking up (and don't tell him you did it.. also don't be hurt if he doesn't realize it for a while... or ever :-)
Have someone watch the kids, and take a picnic lunch of some of his favorite foods.
I love in one of Dr. Phil's books he says to wake up everyday and think of one little thing special that you can do for your spouse. And don't do it because you want something in return.. but just because you love and respect them. I bet you can think of great things on your own!!
Best of luck!
Peace,
B.
P.S. and if you're a Christian woman, pray for him!
