Mil vent!!!

I was just sitting on the couch rubbing my belly and comes and sits next to me starts rubbing and says "it's okay nick if your mom ever tries to do child support on your dad, you're staying with me" I just looked at her like wtf. Was that comment necessary, I'm not saying SO are going to split, were in this together. But if it ever comes to it, HE IS GOING WHEREVER I GO. I don't even know how to lay down the rules with her, she's so dramatic that we have to basically cake walk with her. I could tell her on the nicest way yet she'll turn it around on me & make me sound horrible.
