Person before having dated anyone:
There's good data showing that YYYY, ZZZZ, and KKKK are the best matches for me.
Person while dating an ZZZZ:
ZZZZs seem to be the best match for me. They complete me in so many ways. Our differences are quite complementary and I learn a lot with him/her.
Person after break up with a ZZZZ:
ZZZZs have some potential, but I think the best matches for our type would be YYYY and KKKK.
What happened there?
What can we do to avoid that process and become pinnacles of objectivity?
Wait, do we really want that?
I mostly wanted to hear some random thoughts about it.
