For me, it's a yes. A husband and wife should be together in sickness and in health, for richer or for poorer, till death do they part. There are some instances that one of them will not remain faithful and cheating, or worse affair will come in between. Giving chances to your wife or husband when they cheat is too hard to swallow, but if you have kids you will be confused if you will forgive him or her because you know that the future of your kids will be at stake. No one wants an incomplete family and may affect your children holistically. Forgiveness and giving chances is one of the hardest thing to do but if you learn to forgive, you will set your heart free from grudges and you will be truly happy.
