yesbut,
I went to college at 18, quit at 21, went back at 46, and will finish my degree at 48. My college years 18-22 were horrible. My last two have been heaven on earth. I was not ready for college then. I am now.
Your daughter can safely wait to go back to college until you can afford it...her brain will still be fine! It is not a death sentence
Unfair? Yes, in light of the other daughter. Insulting (his comments)? Oh yes. But not the end of the world....just...a postponement perhaps.
Hoping that you can get out of debt, reduce your living expenses, and find a way to open up some options for yourself.
