I guess when you both work from home it can be stressful spending so much time with each other. My husband and I work both out of the home and the hours we spend together are limited. I can relate to the smelling issue, since my husband I guess can't smell himself at all and thinks that when you wears the same shirt and pants 5 days in a row it does not affect the way he smells. Also he has a habit of going to the gym and then coming back, soaked in sweat and passing out on the couch (he spends most of his time at home on the couch). I have told him several times that I have an issue with that as he makes the couch smell like sweat and body odor. He simply does not care. So I ended up covering the couch with blankets and use Febreeze to deodorize it frequently or wash the pillows covers etc. It's so gross to me!!!
I am much happier since I have started working and spending some time around other people. Apart from that I have started going back to school to work on my career. Kids are older so it's easier. And I am going to Yoga, run and go out with my friends sometimes. All these things have helped me feel better about myself and my life. It does not fix the things that are wrong with my marriage but I also don't focus so much on it anymore and I am all around happier. I guess I am kind of accepting how things are right now. It's not all bad but it's not great either.
