I also think you're going to struggle with forgiveness that hasn't been requested. I don't think that part applies to marriage partners in situations where they've broken their vows. That is a monumental breach of trust, and to turn the other cheek, especially without the other party owning their sh*t, is not a requirement
There are many misconceptions regarding what forgiveness is and what it isn't and it's definitely not 'turning the other cheek'. It also has nothing to do with condoning the behaviour of someone, vows or no vows, that you are trying to forgive. Or returning to a situation where a massive breach of trust occurred.
I'm not trying to convert anyone here but if you are giving advice to a Christian follower, then you should take care that the advice you give does not contradict Christian scriptures or doctrine.
