Regardless of what race or religion, to cheat on your spouse is wrong!!!
If you think that it is right then you did NOT get married for the right reason.

You're born, you take s**t. You get out in the world, you take more s**t. You climb a little higher, you take less s**t. Till one day you're up in the rarefied atmosphere and you've forgotten what s**t even looks like. Welcome to the layer cake son.
