I couldn't do it. From 2008 to 2011, I was 3 credits and half a thesis paper short, had to quit for my health. I had lost too much weight, down to 150 lbs at 6'3", I was falling asleep at work and not meeting expectations. It was horrendous. Props to anyone who can make it work. And to those who were bailed out by the Bank of Mom and Dad, a big fuck you.
Wouldn't you as a parent want to help your children avoid things you experienced? I think you always want your children to go through less hassle than yourself? I personally believe that guiding children through struggles we experienced is not a good idea of parenting. Disclaimer: I didn't finish college as well, for same reasons as you. Edit: I've realized my comment might've sounded like a critique of your parentin…
That said there is a huge expectation in the US. 90% of the time professors or admins mentioned paying for college they assumed people were getting parental assistance or financial aid. For better or worse paying for your adult child's higher education is not really a parental strategy but rather a societal norm all but written into law.
