I read contraeverything original post for this topic....

And while I may not know all that much about demons and possession, I do recognize when a guy has run into a case of "mother-in-law"

All I can say of that I feel for you...I think a lot of married men can understand what it is like to find yourself having gotten married-into a family that is likely all crazy.

just hang in there.
try to overlook their issues.
and , if needed, find other things to do outside during the get-gatherers.
