I'm a single mom, nontrad (two kids) so I totally get your dilemma. My dream school, where I'm currently WL, gives me a 60 mile commute one-way/ 120 mi. a day roundtrip so I also sympathize with your commute.
Go to Texas. It's only for three years.
Could you all relocate to a spot on the UT side of SA?
Congratulations and best of luck!
