He told his parents we were ttc

Jesica • Living the dream in Northern Michigan... Oh, and trying to get a "bun in the oven"
My SO and I are both the oldest, longest together, and most successful of our families. We have waited until we were mostly established to even consider having a baby. Now our parents (mostly his) have pressured us for years. It's always awkward and uncomfortable and I know they blame me for not wanting to try sooner. Anyway he told his parents and his mother called the other day to ask a billion questions. I really am not looking forward to the next get together. I am not excited about the pressure about this. What do you think...? How should I handle this?
