Whatever you do, don't badmouth H to his family, even when they are doing it. It will come back to bite you in the a$$. You stay on as good of terms as you are allowed to be. Don't go overboard, but do what you've always done.

What I'm trying to say is, this all hurts like hell because you aren't just in danger of losing your R with H, but an entire family that has become important to you. Now, blood will tell, but you don't have to be the enemy. Let him burn his own bridges with them no matter what. My H & I are on the verge of a legal battle, but I still email my in-laws every week, and sent them baseball pics of the grands. I never mention H to them at all.

Hang in there, tomorrow will be brighter, I promise.

Having low days are the pits, but sunny days usually follow right behind, in unexpected ways.
