In-Laws are becoming Out-Laws

I'm so tired of being a doorstop. I fought for my freedom with my family, and it was hard won; but with my Hubs family I feel that I can't just say, "I'm out." The answer is simple, but I can't choose to do it, and I feel guilty even thinking about it being done. I don't understand how Papa was able to stay out of my choices so well, perhaps it was the distance from him and my daily life...whatever the case I need that space back. If they hate how we live SO much, they can just leave us alone.
