You know very little. You've had one relationship with a 3/10 cheat and your incel posts are not grounded in reality unlike oknow, other than that it was escorts right? Good for a release and experience but not same as getting a girl normally naturally. That said, the only time I understand your posts is when you express a desire for love, family rearing and how frustrated you are - this is totally normal human behaviour. As you get older, the only single people through choice are usually women who were very picky and it becomes abnormal to be single for others. Divorced with kids is perfectly normal because you still have a family, responsibilities, joint vacations, and could be enjoying dating around too. Always being a single man without a family unfortunately is looked as a red flag regardless.
I'm sorry it's not working out there. I read you are 5ft 5, at this height you really need to be a prettyboy and I have seen such examples with hot girls but usually they have nailed a girl down in their early 20s, for you your past that and with hair loss and lack of such looks apparently from what you say. Full head and average height even with average looks would have been no issue but stack enough negatives and this may happen. The height itself is still not that bad where you can't get a single pretty girl, it's just a few negatives put together, you also seem one dimensional personality wise and that definitely will ruin chances with girls around you (outside of apps).
You're really going to have to take a leaf out of
@Caillou 's book and not end up rotting on forums in pain and finding a long healthy escape plan. This place should be for education, fun and light therapy with like minded individuals - never more than that and for that you need to get help too. I wouldn't give up in your shoes and focus on physical fitness and getting all your hair back - if it doesn't work out at least you tried. Not trying is one of the worst things someone can do. Limb lengthening can easily give you 3 inches without your proportions looking off even 4-5 inches, but I don't know how much difference this would make to your life truly.
