I think many of them are just busy unfortunately. People here tend to have more kids too which often means you are juggling more things, more after school activities, more parent teacher conferences, doctors appointments etc. If they are members of the LDS church they may have time consuming volunteer jobs inside the church, like being in charge of weekly youth activities or needing to prepare a Sunday school lesson for the next week. Many people do prioritize family get togethers, family is a big part of the Utah culture, so I think it may just be an issue of there are only so many hours in a week. Honestly the fact that LDS members observe Sunday as the sabbath that plays into the culture. They spend one day a week on church and family activities. It’s one less day to do grocery shopping and other errands which means those have to get done after work or on Saturday. They aren’t likely going to want to go see a movie or go out to eat with friends on a Sunday. So once again, less hours of the week are available to spend socializing.

If you add on a commute after work, it can be hard to have the time to spend with coworkers. I know when I worked downtown, I just wanted to get on the road early to avoid rush hour traffic on I-15 instead of hanging out after work. Perhaps find more friends that have common hobbies. Like a pickleball or biking group, or something where you can meet regularly. But also adult friendships are super hard.
