Men and konji...

Mind your business bro... Trust me, your friend will find out sooner than you think, her sugary waist and cheating nature will definitely draw her out
If you decide to tell your friend, what evidence will you present to him? And don't forget that she can easily rope you in by turning the whole thing against you..
Let your friend discover her true nature by himself and if you must help,just give him clues indirectly.

Skmoda:

when they are married abi?

That depends on when God will want to disgrace her.

But you can help your friend by bringing up a fictional story related to unfaithfulness and the need for him not to overly trust any babe and place a watch on her to be sure she's not cheating on him.

My brother the thing is so rampant today that you begin to wonder what has gone wrong because even the married women with kids are in involved.

StandUpGuy247:
Your friend should avoid you because you are a terrible friend.

I don't know how your conscience will even allow you chill with him knowing he's been betrayed by the person he will trust his entire life with.

And you will later open that your dirty mouth and call him your tightest man.

My thoughts exactly.

A real friend should save his friend from impending calamities.So what kind of friend do you think you are to hide such destructive information from your friend? Why do you think God took you there at that particular time?
Bross ,please kindly save your friend from this disaster.
I will forever remain grateful to my friend who once informed me of the illicit activities of a girl I wanted to marry. After having the information, I confronted her but she denied it.But I kept a close watch on her and later discovered that she was actually guilty as accused. I had to simply dump her and today she is a recognized side chick to a man that careless about her,while I got myself a humble and trusted woman for a wife.
So do the needful and end the respect and trust of your friend.
