I'm a man, I got married young, I never really lived on my own (except uni).
I've been married for 10 years.
We have two children.
The marriage is a sham, my wife has a succession of emotional affairs on Facebook, which she thinks I don't know about (I have found out in the past).
She acts like things are normal, and gives no indication of what she's doing.
I have made threats to do stuff in the past, but she has seen enough times that I don't carry through. There's no point in me confronting her again, because I'd just look stupid having done it so many times before.
What do I do?
