作为律师? I don't think u can do
I don't know if you are a lawyer or not, even you are, you are not a good one for sure.
Now who can help him most? Nobody but his wife!!!! Even he doesn't love his wife any more, he doesn't need to hurt her, hurt her mom. He still wants her help, he can act as a gentleman, walk away, move out, how difficult it would be? Why keeps complaining to everybody, everywhere?
"我是会介意在别人拉过屎的碗里吃饭的", you're really a sick man. I don't know if ur wife was a virgin or not when u got married with her. If not, if you在别人拉过屎的碗里吃饭的? PLease respect women.
