This person is 38, that's not very old, and according to some stuff I've read is close to the age of maximum average appeal for a man, based on the combination of maturity, financial position, and relative youth. I was 37 when I met my wife, and at least in my circle of friends it's not that unusual. For the OP, I'd just add that some common circumstances (literally either work or school) is the only way I've met women. I don't make a great first impression, and would have no idea how to even try a tinder date. Finding a situation where you get to know people relatively well before exploring romance is my suggestion. That probably would mean looking for a job that has professional women in their late 20s and above, and hopefully finding motivation to want the job that's not just about meeting women, because that would be creepy :)
