but never have this acquaintance seemingly think of me if I’m not directly asking them to hang.

Treating relationsips non-transactionally, helped me. Sure, sometimes I might feel a bit disappointed. That's a hazard of para-social thinking. Relationships have asymmetries. Hence the friendship paradox: https://en.wikipedia.org/wiki/Friendship_paradox

Maybe I’m a boring person?

Well half of all people are more boring than average...But mostly adult lives are complex. You probably don't rate as highly as someone's child, partner, or established social circle. These are long term relationships. Good luck.
