I'm just going to assume you haven't seen any modern divorce statistics, or seen the absolute damage divorce can do to a man's life.
First of all, in regards to the MGTOW comment, I think what you said is projection; this belief that one cannot be happy and single/unattractive to women. I guess Catholic or Buddhist monks are coping, by that logic. Besides, some MGTOW actually date and have casual sex by their own admission. MGTOW isn't a vow to celibacy, although a MGTOW can choose that option.
Second, you can be happy and be unattractive at the same time, because if you actually listened to or read MGTOW content, you'd know that modern women aren't worth it. Think of how the divorce industry destroys modern men (You have seen the divorce statistics, haven't you?) False rape allegations are also a real thing, not to mention the Duluth model, child custody battles, etc. Women are your legal superiors in the modern Western world, and MGTOW who reject marriage or relationships have very legitimate reasons for doing so.
Besides, you're older. The male sex drive wanes with age, and women aren't going to be as interesting as they were in your teen years.
Not to brag, but I don't care about women anymore, because the MGTOW community spelled out the reality of what women are actually like. It amazes how some fellow incels here believe the lie that women will make them happy...
