<human>: A co-worker I occasionally hung out with is about to rip the life out from under his wife and five kids. He made up an elaborate story to tell his wife, and told her he was going on a two week military deployment. In actuality, his "girlfriend" from Germany flew here to the US and they stayed with each other for those two weeks. 

He is now saying he is going to divorce her and move to Germany, and leave his four children (ages 1-6) and his pregnant wife here. He brags about it to everyone at work, and it seems like the only person who doesn't know is his wife. He justifies this by saying his wife "might have" cheated on him while he was deployed years ago. He also uses the excuse that his wife overdraws their bank account and he had to pawn everything, but in actuality he only comes to work about 20 hours a week now. So he is at fault, not her. 

I completely despise him now, and have tried to talk as much sense into him as possible, to no avail. I don't know what else I can do. I feel very bad for his children, and having kids of my own, I can't imagine them homeless because of his extremely selfish acts. Suggestions?

Can you give me a shortened version of the text?
