Some great advice here already! So I’m going to suggest something novel:

Consider “settling,” just a tiny bit. What I mean is, don’t be so quick to assess someone new as A Partner…potential or otherwise. Try letting gals in who are attractive enough and carry themselves well, seem sane, easy going, smart, etc. Shared values, that sort of thing. A female friend with potential, if you will. See where it goes; be open to being surprised, pleasantly or otherwise.

I’ve seen so many younger men “auditioning” mates with unrealistic expectations about “clicking” or “just knowing” — and winding up as older bachelors who have never even had a chance to practice being in a relationship.

Yes, like literally anything else worth doing/having, it takes practice!
