Clear that entire IL family thinks H is dumb to be doing this and they do not like OW. But again, they will support him (and her) when it comes down to it.
I'm glad you recognized this. I wonder about all of my ILs. None have spoken to me about the D and I don't think that any of them know about the OW. But no matter what, I know that it won't be me sitting around their Thanksgiving table - blood is thicker than water.
Sit tight. Remember that you have no control over what H does and what he doesn't do. Continue living your life, taking care of your D and yourself.
