I was also wondering if the OP was driving the potential partner crazy with interruptions and minor details to the point that they couldn’t get a word in edgewise or describe their vision for the big picture- then in frustration, those people had to withdraw before they said/did something they regretted. Perhaps they resented the micromanaging? Bc I don’t think this often happens. It’s not a secret red flag to be aware of. Someone rudely leaving a disagreement has a note of finality to it. Who re-enters this voluntary process?
