Me too. Let me guess - blackfoot is actually a blond, blue-eyed Swede? Just kidding.
I'm glad that things are good between you and W. I would work on that IL thing. What happens if you "whisper sweet nothings or do something mildly sexual in the presence of the ILs?" I think if you can do a little butt pat or hand holding or inside reference in their presence it will go a long way toward establishing you W as a grown-up and your marriage as equally important as the parental R. What do you think?
