Scary story

I've heard a scary story from my colleague.
She talked about her old male friend. She have known him so many years.
One year ago, he got married. However he was not happy in his marriage life.
And he asked her some advice.
The advice she made was he should have children and develop his family.
One year later, his wife got pregnant however this couple decided to split already.
Of course he is adult person who made decision his life.
So my colleague has nothing to do with it.
However I can see when she made advice she did not even imagine this conclusion.
What is more, my colleague is now his girlfriend and considering marriage.
Wow.
I feel so scared.
She is so nice and understand people so people often take her advice straightly.
Life is so.. what can I say...life is so scary.
