How to trust after cheating?

If you are in a classic monogamous relationship and you have been cheated on, the question "How to trust a person again?" is no longer appropriate. The answer to it is one — no way. You will no longer be able to trust this person the way you trusted/trusted before. And you have two options: either be in a relationship with him further and just accept your distrust as a given and inevitable, or break up. Well, to live, remaining in a relationship, to suffer and be tormented by the question "How to trust?" — this is not an option. It's just a neurotic mockery of yourself and nothing more.
