Don't meet strangers or cheat on your SO with someone you know or work with, period. Or just break it off and find someone new, why act dishonorably and making others miserable? All in all, I don't know why people cheat if they are happily married and their spouses are great. Seems to me the risks far outweigh the rewards. Then again, I don't understand why people get married in the first place.
