Explosive End
Cheating on your spouse is never a laughing matter, especially involving a co-worker. Sadly, 10% of affairs happen with a colleague from work. It’s probably because of the constant close proximity to them and the fact you see them every day. I can understand why this person wanted to keep their affair a secret.
However, hooking up with someone from the office is a bad idea, even if they have a nice smile and a great sense of humor. Didn’t this person ever watch The Office? “Don’t dip your pen in the company ink.” At the end of the day, no job is worth sacrificing your marriage or your dignity.
