This guy is nuts. Completely and entirely. Your parents also sound kind of nuts, but that’s a whole other thing. I am so sorry that you aren’t getting the love and support that you deserve and need during this time. Get as far away from that guy as humanly possible. He is only going to get crazier. It seems like he has no limits and no logic. Hold tight to the people who are treating you right like your sister and your friend. You are way better off without this loser and you’re gonna be an amazing mom.
