I received an anonymous letter telling me that I was cheated on, what should I do?

When encountering such a thing

First of all, make sure if someone is playing a prank

Check the authenticity of the video

If it is true If so

You can have a good talk with your wife

See what he says. If he apologizes to you and hopes you give him a chance

Then Just forgive him once

Of course you can also choose to divorce

Think about it yourself!

Good luck
