I can't speak for all men but women are the main reason why men cheat.
I married my wife when I was in my 20's.
I'd come straight home from work, I was always in a hurry to come home to my family and the moment I got home I felt unoticed and unwanted.
She'd spend hours on the phone with her sisters and friends and by the time she realized something was missing it was a little bit too late. I found a woman who came and stole my heart away. My best advice to the ladies out there pay attention to your man and love him dearly because if you don't someone else will.
