Infidelity is unforgivable especially if you are married and have vowed in the eyes of the law to be with someone. It is also destroy a marriage or relationship.
Can you forgive them and give them another chance . Because of the welfare of your children if you already have and you do not want to destroy your family. Or you want to separate because you're hurt..
I think there should always be a second chance, an infidelity is always because of sex with another person, and yes, maybe it is a lack of respect, but I think everyone deserves a second chance and more when there is a family, children involved, Separations are not very pleasant, they always have to seek to be together despite mistakes.
