That woman, from the beginning, if there is an interest in pursuing a relationship, should be honest about that past, if she is truly repentant about it, at least, the man can make an informed decision about what he wants to do.

This is why many relationships don’t last, the Spirits of these people are warring. Also she may even suffer from Mental Health because of those Spirits, which is a proven fact.
