not dating to marry, not dating to separate, but a secret third thing (dating to enjoy being with a someone you're compatible with for as long as you both enjoy each other, no matter if that's months or years or the rest of your lives)
There is no situation where it's appropriate to publicly say your wife/husband isn't your spec. None. 💀
Your spouse is your life partner, & anything that could make them feel "less than" should never come from you.
So saying they weren't your spec at first glance is bad, & whatever explanation or compliment you add afterward doesn't erase that “you’re not my preference at first but...”
Some things simply don't need to be said.
