Soliek, Its a personal choice if you would cut somebody off. But keep in mind that there are no such things as “Perfect People”. And it sounds as though you are looking for that. If you want to operate like that you will be likely cutting off from everybody at some point for daily offenses and “wrong moves” in every sphere.
The point i am making is that we do need to be flexible at some point and if a person makes a mistake and abuses and lashes out or hits his friend, wife, etc, its ok if the victim wants to forgive. Its ok if the attacker wants to admit his weakness in charachter and work on himself and make amends. Teshuva.
We are not in a perfect world. But its a personal choice,,, if you cannot forgive that then don’t stay with them. For me personally, I could forgive a physical slap if it were to happen, but I cannot forgive disloyalty. NEver.. That hurts too deep. THe marriage would be over.
