I dated a few crazy people back in the day, but the craziest was a girl I dated right before I met my wife.
We had been seeing each other for about six months when I found out she had gone to see her ex one night. I was 25 and she was 23. I was already mad about that, but then I learned her ex was 44 years old. She had met him when he was co-teaching her Bible study class with his wife. Not his ex-wife, his actual wife.
Somehow, when everything came out, the church took his side and his wife was the one who ended up leaving, even though he was the guy running around with 20-year-olds.
At that point, I told her I needed some space. She responded by stalking me. Eventually, I had to be blunt and tell her, "Leave me alone. It's over."
Fast forward two years. I'm engaged to the woman who is now my wife. My ex runs into my parents at a restaurant and walks over to tell them that I keep calling her, begging for her back, and crying because I'm not marrying her. My dad called me furious. Then he realized she was lying because, according to him, the crying part was completely out of character.
Fast forward again. About three years ago, I became good friends with a guy after we discovered we had both dated her. When he got married, she actually called his mother multiple times claiming that God was worried about him because he had married a "devil woman."
