Infidelity is an absolutely sensitive topic. It is always best to avoid it completely. This is not just true in marriages but in relationships also. Hearts are very delicate organs and trust is hard to acquire. But if it happens, it is necessary to properly assess the situation. People make mistakes and I believe that they should not forsaken for such. In view of the efforts and sacrifice put into relationships and marriage, forgiveness is a very great option. But in circumstances where one partner is consistently unfaithful, I do not consider that such relationships should continue.
