You planning on having kids? If not, maybe deprioritize attraction and focus on someone with a personality.

Bonus: you won't feel nervous or creepy talking to them.

Man, loneliness sucks! Best I can say is try and fill your free time as much as possible. I met my wife online, but that landscape has completely changed since we got together! At the time, I was in my late 30s and pretty much only out of my apartment for work or gym. If I hadn’t met her, I’m pretty sure gym time would’ve eventually dwindled to zero. Even if you don’t start a new relationship, you’ll be busy and around others. Better than Netflix being you closest “friend!”

Wait, you only are attracted to women in their 30s still, at nearly 60? Oof I am almost your age with kids that old. I can see why you are worried about seeming creepy.

Best of luck to you, in any event, and I do think if you open your window to women who are similar attractiveness to however you look, your prospects will be good, if you had a long run of a relationship you can again, you do know how to live with someone. That's a valuable life skill. And I agree with d00phy, get out in the world and do things, you will meet people and make connections, that helps.
