Is there any offence you can never forgive your partner?

Probably infidelity especially coming from your own spouse. Though I'm not married yet, I do know that it hurts when someone you love cheats on you regardless if you're married with him or not. I can't really say that I can never forgive him if he cheats on me.. But for sure, it will definitely take some time for me to forgive him, some time to heal the wounds and also some time for me to move on.

Very difficult would be adultery. That would be an ultimate sort of betrayal. And one I don't think I could stop myself from thinking about. If it actually happend, it would be on my mind daily. Probably not something that is easily gotten over. Let alone forgiven.

My wife told me she would forgive anything but infidelity This is a big thing for most women and men. You have broken the trust of your parnter and if you have relations with another then they will always wonder who you love in your heart? I can see why men and women cheat. It is the urge to see some one who makes them excited and it is an ego boast to play with fire. But when you play with fire someone is going to be burned. Some culture have a man who is allowed a misstress or two..but it is not a good thing for the family as this causes much confusion in relationships later on. People may forgive your partner but they rarely forget the sin. Children are said to love their parents but rarely do they forgive them..an old saying. When you are older you will see the wisdom of a lot of old sayings..but when you are younger you like to sow your wild oats...more for men then women.. To error is human..to forgive divine

yes, cheating is very hard to forgive and forget. it always comes back and haunts the relationship. with cheating comes also dishonesty. it is very difficult to justify and understand cheating from any point of view. i think that is the offence that i wii find difficulty in forgiving my partner.

yes - betrayal. Definately betrayal - of any kind. It's unforgiveable in my mind.
