I can attest, got out of a long term relationship a while back and have had absolutely no interest in getting involved with anyone to any degree, and I have been getting way more attention than I’m used to. Having no interest, however, just leads to me awkwardly smiling, a moment of silence while they’re waiting for reciprocation, and then me saying, “Thanks. Well, you have yourself a good one!” and scurrying away to play Red Dead 2.
