If you guys are new to the poly lifestyle, then I think there should be TONS of communication. Even if you're not new, I think there should still be tons of communication. That is one of the biggest pieces to making this way of life possible. I think you have every right to ask as many questions as you feel you need until you're comfortable.
I always get a lil worried when someone starts avoiding answering questions from their so. Just my opinion of course.
Live life to the fullest 'cause you never know if you're gonna wake up tomorrow!
