Reb, if I may, stop looking of your shoulder. Remember the good times for what they were. An enjoyable experience. Create the life you want.
And from a man's point of view, the chewing tobacco and extra weight, he's doing what he wants to do. Being comfortable. We quit nasty habits and lose weight for....WOMEN. At least 60% of the reasoning behind it anyway.
As for yourself, do what YOU want to do. If you've wanted to see how it feels to be a redhead, blonde or whatever, go for it. Buy some new clothes, nice under garments too. Feel sexy. He'll notice. Change up the house. If you've wanted new furniture, get it. Make the bedroom YOURS. Not something you used to share.
In short...do what your H is doing. Only with a positive, responsible spin. Isn't he using many DB principals without knowing it? Hasn't that caught your attention. Isn't that funny?
Do you. What you've always wanted. Because your worth it.
