Wow, Getting ILYs, wish I could hear that from my W.
Did your wife work before you had children? One thing my W brought out in counseling was she quit her job/career after our 3rd child (she started babysitting at home) and looks back now and thinks where she could have been if she continued to work. This was one of many things but I think it was a big one as she has seen me advance in my profession.
Read DR, set yourself some small goals, work on yourself. Nothing you can do to change her except make changes in yourself, she'll notice. Don't push R talks, if she brings the subject look her in the eyes, listen to what she says and validate.
My wife is in a MLC, she lives with our D24,D24'BF, and our GS. I've made changes, some she has noticed, but some are on hold. (I has quad bypass surgery 10/15). I only wish I'd found DB & DR when she was still at home.
I wish you good luck my friend, just know there are others out here for support and a friendly ear.
