Public tears and a freaked out hubby

So I am 6 weeks pregnant and my fiancé and I were going to a nice steak house for dinner since I had been craving steak. Well on the way into the restaurant he said some things that upset me. Granted, they upset me way more than they would have if I weren't pregnant. At first I felt so much rage and then all of a sudden I was fighting the urge to cry, so I went to the bathroom to calm down. (Keep in mind he has never seen my pregnancy emotions in full force because he is usually at work when they hit) I came out and started to address the way I felt to him and I started talking louder and louder as I got angry again and he kept shushing me. And then the tears started again but worse. He gets all wide eyed and goes, "wow. You really are emotional!" I was like, "no shit!" And went back to the bathroom to hide. I calm down and come back to the table. Everyone is staring at me now wondering what the hell is going on with us. As soon as I sit down he's talking 90 to nothing and being over chivalrous which is out of the norm, "I got you a Sprite in case your tummy hurts, here taste this it's really good, you're so beautiful, here do you want some bread? Butter?" And he started cutting a slice of bread and buttering it for me. I was like, "why are you being so nice?" And he looks at me wide eyed again and his voice cracks when he says, "I'm scared!" I friggen LOST it. At first I was laughing uncontrollably, snorting and everything. Then people started staring again and then I got the biggest, most over whelming urge to cry I have ever had. But it was odd because it didn't feel like happy tears because I was laughing so hard. Not to mention I couldn't stop it. I try to get up in a hurry to go hide in the bathroom again and knock off the bread and butter, almost spill my drink, trip on the leg of my chair.
