I can empathize with your situation. Although I am not married nor have any children, I am finding myself in a very similar situation. I have already obtained a teaching credential and a master's degree in organizational management; however, I am missing the science degree that would provide me with many options. Albeit, I have obtained a Medical Secretarial Degree, it is not a RN license.
I am assuming that the nursing will take up much time; but I have talked to a few moms that were juggling teenagers and still were completing the second year of the ADN nicely. It is a constant juggling act I am told. I would assume that since you have children that you may place more pressures on yourself and more guilt on yourself than your husband ever would. :)
I once set up the University of Phoenix in Fresno and Bakersfield CA with the nursing programs: BSN, MSN, RN-BSN, RN-MSN bridge. I may have to go that route down the road since I do not have a BSN or MSN. I am told that that shouldn't be much of an issue. I completed the MAOM degree at UOP and another student in my student group was a nursing supervisor who also wanted a business degree to round out his experience.
I am getting off track; but I just hope you will be able to provide yourself with the time necessary to achieve your goals. :) All my best to you and hope you will enjoy the remainder of your A&P courses! :)
