Question: what if you fall in love with best friend.? you are married and so is he

Answer: Don't do anything impulsive.  Let this just sit for a while.  If it's really love, it will last long enough for you to really think hard about the situation.  Then whatever you decide to do, you just have to be completely honest with all parties concerned.  The situation is bad enough without deceiving innocent people to make it worse.
