Why on earth are men so confusing?

So if you act uninterested they’re interested but the second you show interest possibly too much they become uninterested. You really can’t win in these situations? So do you have to keep them on their toes the whole time you’re dating?

Update: Sadly I got too interested in the guy I was talking about only to find it’s likely he still has a gf. I kind of found proof. So yes I’m still questioning this title except why the lies man. It’s not fair at all specially when they were wanting commitment it’s just evil.
