Thanks to all for the advice. More details:
Girls college is completely funded. I am of the philosophy: one car, one degree, one wedding. If they want more than that, they can pay for it (or at least think that way. They have no idea (and I'm not telling them) that they will likely inherit enough money to allow them to be beach bums if they choose to for the rest of their lives).
I am confident that our financial situation can allow us to RE now, but DW is a doesn't trust the stock market. We have been going over the numbers and having the same discussion with the same outcome for over a year now.
I worked part time for a few years and really enjoyed having more "me" time and time to do all the things around the house that needed to be done (which now consume my weekends). Unfortunately, my job situation had a big shake-up about a year ago and now I am back full time without an option to go back part time. My non-compete clause prohibits me from finding part time work elsewhere in my area for two years, should I leave the organization.
Last, DW thinks I will be bored in retirement. I'm not worried about that and have many interests/hobbies outside of work.
I retired when my child turned 7 years old. I have a decent traditional pension (enough to get by one) for which I made my child my joint annuitant (in case something happened to me). In addition, I had (have) an investment portfolio. Between the two, I decided it was good enough to provide for my child.
I had many people whom I worked with tell me they couldn't believe that I would give up my J*b given college years ahead. My response was that if I were to wait until college was completed, that was another 13 or so years! No way since I was FIRE ready.
Part of the reason for retiring was that I was traveling a lot. I would be home only about half the time, and I felt I was missing out on my child's growing up. About six months after I left work, my child developed a serious unknown GI related illness. I am extremely thankful that I was home during this time and able to devote a lot of time and effort on it. [He is much better now.]
Since then, I've gone back to work, but not because I had to. I started teaching part time at a local college, and since then have gone to full time. I love being home, get to spend a lot of time with my child, but part of the reason in going full time (besides the health care) is to try and instill work values.
One suggestion I would have if your spouse is retirement shy due to not trusting the stock market: Divest some of the assets into cash equivalents, enough to provide 2-3 years of expenses. While this many lower your long term returns, the cash safety net will help your souse (and you) sleep better at night when the next rough downturn comes (and it will). I left my j*b in the midst of the great recession of 2009. It was only the cash flow from my pension PLUS a couple years worth of expenses (w/o the pension) in cash & equivalents (some great Penfed CD's at the time) that gave me the confidence to go for it even though my portfolio was getting whacked daily. (In fact, I was buying equities during the Spring of 2009.)
