Got it!!!

So, there are certain members of Layne's family (my fiance) and certain members of my family who are unhappy with our relationship, and seem to be hell bent on making things as miserable as possible for us.

It's tough. We're both trying to take the high road, turn the other cheek, be the bigger person, etc. Swallowing one's pride is nauseating.

I've thought of the perfect analogy:

With our two families it's like vomiting and diarrhea; we're getting it on both ends.
