I can't say I've had any GFs or wife betray me. When I was in high school I had 3 GFs in a row dump me. I learned that if a person doesn't want to hang out with me they aren't going to be any fun to hang out. SO as soon as someone says bye, I'm over them and moving on.
Hello , I just wanted to say a couple things about betrayal.
You know its wrong,and in marriage it is compared to someone close dying.
It is never justified ever.
If there was one thing I could tell people just getting married it would be protect your marriage and under no circumstances ever betray the person you love.
