KC,MO. Mark is a met addict and doesn’t know what is the truth and what’s not. When I dated him he was also sleeping with his exgirlfriend. She didn’t know he was sleeping with both of us and either did I. When I found out he messed up. Mark is a self serving, dishonest, uncaring addict. He lives with his dad because he lost his house due to drugs and gambling. He is smooth and you want to trust him but don’t.
