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..
It naturally depends on the couple. I've known of a couple who moved forward after a case of infidelity. Others actually stopped and broke it off. In my experience, i can't get over being cheated on. Knowing that, i would rather let my children live with a broken family that them being in a dysfunctional one. At least right off the bat my kids would face the problem head on and actually adapt to it. Others could live with the fact that their partner cheated in them, but then again that's them.
