Different perspective here.
Let's say he's not being emotionally abusive and is reacting to his mental health issues. He is not socializing himself. He stays at home and doesn't go a lot of places. I have generalized anxiety and have BIG issues traveling and going to other places to visit. I can go anywhere with my husband now, but I have to plan the trip so I know how many miles to the next town, what to expect on the road such as being out in the boonies away from civilization...my dad died in the Arbuckle Wilderness in Davis Oklahoma and I know that plays a huge part in my anxiety.
I used to enjoy traveling. I would get in my car and drive about 3 hours away to go stay a weekend with a friend just on a whim. I would crank the windows down and put Alabama in the 8-track, hey, it was an older caddy and very comfortable...lol. I could not do that now without at least 1 adult in the car to call 9-1-1 in case I had a panic attack or got anxious. He may be having an honest mental health issue here.
He sits at home the entire time you are gone and pouts about how you chose your family over him. He may not mentally be able to go and wants you to stay with him instead. He obviously needs to get over this.
The only way he will get back to a more normal person is to deal with his issues through having a therapist who specializes in anxiety and depression or he may be albe to just use the services of a case manager, they will help him set goals for himself and monitor his progress but do not do the "sit in the chair and talk for 50 minutes" type therapy.
I feel for you. I have a husband who is an introvert and has to have his alone time every day. One of our therapists, we have gone several times throughout our nearly 20 years together, said he was the perfect hermit. He could live on the side of a mountain, have no contact with other humans as long as he had the internet and TV. The once a year trip to town for supplies should give him the perfect amount of social interaction, if someone tipped their hat and said hello.
It can be hard for two people with different types social interaction personalities to meet on common ground. He needs to let you have your family time. He needs to go with you for at least the family holidays like Thanksgiving and Christmas, perhaps Easter. Those are huge family events.
How about inviting the family to your house next get together? A huge family Easter Egg Hunt just might be a lot of fun planning. Every one can bring a dozen filled eggs and their own baskets. You can hide the eggs for little ones first then the bigger kids later. It could be a fun filled day in the park and everyone bring pot luck to eat.
I can remember as a child going about one weekend a month to the South Eastern part of Oklahoma to visit relatives. My dad was next to the baby of 14 kids, 11 grew to adulthood. I have 47 first cousins and they all got married and had about 3-7 kids each. I am next to the baby of the nieces and nephews. I have hundreds and hundreds of relatives alive today. We have a family reunion in Oklahoma every few years and I haven't been able to travel that distance in a while. But I am friends with so many of my relatives on Facebook and am able to keep up with their lives that way.
Good luck with your travels and vacation plans. Maybe try planning some special weekends with just your family. Some short road trips, and see if his focus on being neglected changes some. When we visited Provo and SLC we had so much fun going through Vernal seeing the Dinosour excavations and the museum. You have so much to see and do in your area with Arches, Vernal, the Golden Spike museum up in Ogden, Bryce Canyons, so much diversity in one state. Plus you have so many other places within a days drive in other states. Yellowstone, Grand Canyon, Pikes Peak, and more.
Here's a link to some activities in Utah to do with families.
I don't go to church anymore but my husband wants us to. I find I still need that spiritual interaction and feel pretty empty inside. I want to go to a different church but hubby won't even consider it. Some day I probably will find another church home that I can go to on my own. Don't let go of Family Home Evening. It doesn't have to be focused on lessons and singing primary songs. It can be about making cookies and just loving each other.
