Looked through your list and though I don't mean to impose my criteria on yours, I'd suggest it would be cool if, in your descriptions, aside from a general impression, you had in mind helping to sorting out games according to a variety of factors. Personally, I'd want to avoid both "true NTR" (that leads to separation) and cuckish, demeaning, defeatish endings for the MMC (including anything where he's clearly juniored in the relationship, whether or not he ends up enjoying the situation, commonly referred to as "taking the back seat"). Probably your title doesn't mention netorase or sharing for a reason? Either way, that's the theme of this thread, so, to suggest that there are games in your list that fit the bill, it would be great to know at least which ones have nts/sharing paths.
I did look up a few, looked for posts and walkthroughs and still couldn't see anything that assured me they'd me worth playing (due to preferences mentioned above). Two examples are wives Hana and Misumi, couldn't clearly tell if there would be a path on either of them for the MC to be a man and reclaim his wife, without taking a path that avoids the NTR altogether.
Again, don't mean my criteria should be universal, nor that everyone on this thread shares them. I also hate RPGM with a passion, with all that moving sprites around a blocky map that feels like wasted time these days (though I definitely enjoyed games that look worse... Back when the best rpg games looked like Ultima I-V. Just a little rant).
