@Indian-Hubby,
You're conflicted in your emotions and that's ok. You are trying to use rational thought to justify being wronged. The problem is, there is no justification. You're just being wronged.
So there you have it. She's cheating on you and you allow it. When this affair is over, there will be another and another and another after that. When people show you who they are, believe them. She cheats. That's who she is.
But you're not like that.
If you want to stay in this marriage you have to accept you'll always be the second man in her life. You don't have to like it or even her. "Love" won't enter into the equation. It will be silent and easy.
If you think you deserve more out of marriage and for yourself, file for divorce. She probably won't even attempt to fight it - she knows why.
I'd rather be happy and alone than miserable with someone. But that's just me.
What do YOU think?
