Hey Southergirl, welcome!
How old are you? I know you said he is in his 30's, are you as well?
Seems like a couple of things, he seems to be bringing his work stress home with him, alot of people come home and are "burnt out" from a long day at the office and just ned time to relax.
My wife is that way, her outlet is computer games, she needs a few hours on the PC before she talks to the rest of the family.
It is a Ying yang thing, I am the sexual one in our relationship, she is not, I think she could easily go the rest of her life without sex, now that she has three kids...LOL But she gives in to my ways
But I was saying I know alot of couples were one is the sexual one, and the other is not, which is weird.
As for the decorating thing, I am very particular and my wife has "horrible taste" that is why I am conviced I am ugly, because my wife likes ugly things...LOL
But really she has zero taste when it comes to design, I grew up with 5 sisters, So I actually have some sort of taste.
I just think your husband is caught up in a "routine" eat, sleep work, etc. It happens.
I know my self and others on here have "date nigths" with our spouse, where we go out and have dinner, comedy club, etc. Something to break up the "habit" that is life.
Best of luck, sounds like he is stressed out and just caught in a rut.
