Considering relocating to Texas

Even with a single income, I would think an engineer's salary should support a decent standard of living almost anywhere in the country. Have you looked for higher paying jobs that are available? Even government jobs may be a decent option for job security, benefits, etc.

That is very true. I currently make significantly less than the industry median due to working at a small startup company; there was a promise of "oh you'll make lots of money when we start selling our product!" but I don't see that realistically happening for a couple more years and I can't keep living this way for that long. There are a few interesting positions I found with much better pay in northern CO but then there's still the issue, I just really don't want to live in Colorado any more for the other reasons I mentioned earlier.
