I know there's a lot of vets on here who have given you a lot of great advice but in your last post, you mention telling W about how unhappy you are and how you want to work on yourself.
I don't think there's any need for that. Just go and work on yourself. It sounds like you're home a lot with your children so uyou might need to find a hobby you can do at home but your W will notice if you start doing things. If you're not there for the "awkward greeting" and she has to come and find you, that's better than being at the door like a little puppy dog begging for some attention.
The only other thing I could suggest is setting up a boundary where she gets home at a decent hour so you can go out.
