Ok, I’ll go out on a limb and make a few recommendations.
Since it sounds like you will be only the maid and not the mechanic you might consider a single engine ( a little bit more difficult to learn to drive in tight quarters, but you will need lessons from a Captain either way).
Decide what your budget is going to be including insurance, sales tax, slip fees and champagne. Only look at boats you can comfortably afford. Even if you mainly live on the boat you’ll have normal maintenance (oil changes, batteries, thru hull fittings, bottom paint, pumps, seals…). Wood is beautiful, but fiberglass needs less maintenance.
A boat is a lot of work, and you will undoubtedly learn about all of your boat’s systems in the process of owning one. If you embrace the challenge it can be a great experience, and good post divorce therapy.
Best of luck.
