Uhm, Seamus, you kind of insisted on doing it all with Aidan. When Matt arranged to put him in daycare for extra days to give you a break you told him no. Yes, taking care of a small child is exhausting but you had to be the hero so don't blame Matt. Matt isn't throwing being Aidan's parent in your face, he's trying tell you he feels like he's being closed out. Also, as you were reminded at the hospital, ultimately responsibility for Aidan falls to Matt. You need to stop the passive-aggressive behavior.
