I would be angry! Why bother getting an education if you are not going to use it? Please, I am not using my Ed degrees to stay home and help my kids with their homework . I could have done that without them.
Sometimes life changes and your original plans (made at age 21) don't work out and you adjust.
I got my MBA... it paid for itself in about 2 1/2 years (yes, my salary increased that much). I was in a high pressure, many hours job. When kids came and my husband started traveling 3-4 nights/week for work, I stopped working. I didn't think it was fair to a kid to be in daycare 7am-7pm daily, so we made changes.
Did I plan on quitting? No.
Did my education "go to waste"? No. I used it, it paid off.
Do I use it now? Not directly, but it indirectly made me the person I am.
I view my role in life to keep the household running, the kids happy, and the traveling spouse grounded. I am the glue that keeps our house together, the rock that holds us from flying away, and WD40 that keeps us moving in the right direction.
ymmv.

You do seem to have all the answers. How many kids do you have?
