Most Helpful Guy
It's not the other girls personality that made him cheat. It is HIS personality that made him cheat. Don't focus on what might make a guy cheat. He is either a cheating type or not. It's up to you to choose better. I bet you had warning signs (a feeling in your gut maybe?) at the beginning of the relationship. Listen to that warning next time. It will save you time and pain. Good luck!
