Thas gotta be a tough situation massive. You obviously care about your wife and her family and their feelings which I can dig, but thats gotta get difficult. Do you ever think it might be worth approaching her about as opposed to hiding things, or worse having her find out on her own? Not trying to tell you how to run your marriage, but for me having to conceal it even in my house would be tough and if she found out it would be 1000 times worse then if you tell her. Obviously now is not the time, but it is something you'll have to eventually deal with. Sorry to hear about your tough times, hope he pulls through alright bro, you have my prayers.
