If he decides to stay in Texas, Austin and College Station are quite different so I assume he would have a clear preference in where he would rather live. Or, if you already live in Austin and he wants to go away for school, that would be a factor.
My baby is off studying engineering in Boston while I am in Texas. He loves school and Boston. We have family in the Boston area so he has local back up, but that isn’t the same as a parent.
Good luck to your son and you have my sympathies. I, too, will have my second leave the nest in a few years.
