“Auburn pluses you’ve expressed:”
You missed a big plus of Auburn:
“I love the atmosphere”
Given that, and assuming the OP didn’t love the atmosphere at the other colleges, it’s going to be tough to dislodge Auburn as the top choice.
“I don’t think she would be upset with me going for my degree at Auburn.”
If this is the case then OP should confirm the affordability and go to Auburn. You don’t want some one at college second guessing themselves.
