A lot of what you wrote is correct, except for this statement.

Any person who is "cheating" with another is not just hurting one family. He or she is affecting the whole chain of relationships that exist between the two. Husbands, children, family, friends often times work, financial and so much more. And these day the social media makes it even greater.

Nobody is an island and nor can they exist without others. It's who we are as humans. The egotist thinks others exist for their pleasure.

Wow, I thought this forum was all about aviation. Since the talk is basically about relations maybe it can switch to boats, cars or airplanes?
