On the other hand, you could get a lawyer to vet it. Or, if you wanted to give it more heft, get a divorce lawyer to write a chapter or two about the legal ramifications or how a lawyer like him/her see these things. You could pay the lawyer to do it or give a cut of the profits. In addition to allaying your concerns, it might also let you charge more for the product.
I say all this because I'm not sure how easy it would be to sell a slice-of-life type of eBook vs. How To's, which are all over the place.
Slice-of-life would work on a blog, though, which you could monetize with Google Ads, ads from other networks, etc., but that's not likely to be as good as an eBook.
Though you could also monetize it by being an affiliate for related eBooks and regular books -- if you went to ClickBank.com you could probably find some related eBooks that you could get commissions for and similarly with Amazon w/r/t dead-tree books.
One other idea: start small with a short report -- say 10-20 pages -- and sell that cheaply, say $9.99 or less--and see what happens. And/or give it away to build up a mailing list, if you can think of how to sell related stuff. This sort of thing is done a lot.
