Men are from Mars. Women are from Venus. You’ll drive yourself insane trying to figure out or second-guess people who behave as if they’re having a great time with you and then disappear. I know you don’t want to hear this but from my many years of dating experience way back when, I learned that a lot of times their disappearance has nothing to do with you. So do yourself a favor and let it go. Look at it as dodging a bullet. You’ll never know why they chose to go that route and really, it’s not worth the energy trying to find out.
