Zero & zero. We started dating in high school, got engaged during college, and got married the week after graduation.
I will say that some people do surprise me, though. I’m a guy and even I saw all of these red flags with one woman I knew. She was going to become the third wife. Dude had two ex-wives, children with both of them and had a kid with a third woman as well. Fast forward, he cheated on her and the woman he was cheating with married him. So apparently, someone out there thought that this guy who is cheating on his third wife would be a good one to marry and become his fourth wife. I told my wife that he’s a train wreck and I don’t understand any woman who would even consider getting coffee with him once they knew his background.
Different strokes for different folks.
