Awe but not all shiny objects make good investments. All is not gold that glitters!!!
Could be the emotionally unavailable men are a challenge that you seek to win.
Could be you are repeating what you know. I would never have thought my Dad was emotionally unavailable but turns out I was wrong.
Could be you are mirroring that unavailability, feeling close to someone without having to risk your heart fully.
It’s worth investigating, maybe get some therapy to help you figure out why and then a plan to break the bad habit.
