My husband told me last year that he wanted a divorce.
Sorry to hear that how did things turn out did you two make it work or going through the process now? 
Well, he didn't have a real reason honestly - just said he wasn't happy.  But it's a  year later and he's still here so - LOL!
He has to be happy if he still there marriage is important and he has to be open in communication with you instead of pulling the divorce card.
