Flipperjo, the only thing I would add is to make sure you STAND YOUR GROUND! Don't let "them" (everyone from your DH to your MIL) suddenly decide that everything will fall into YOUR lap! I've seen it happen in situations like this, where the guilt-laden DH gets manipulated into accepting that responsibility - but who does it actually fall to? You! DON'T GO THERE.

I don't mean to sound cruel or heartless, I just think that I can see the writing on the wall, and don't want to see you railroaded into an out-of-control situation.

Stand your ground. Yes, be loving and kind, but protect your space and don't let them make any decision that will profoundly affect YOU without your full consent and input.
