Overreacting to certain things mentioned 1 week postpartum?

I am one week postpartum and although Father’s Day is tomorrow I found this comment this morning to really blow my mind. We have twin 4 year olds and a newborn, and my husband mentioned “so and so asked me if I wanted to go golfing today”. It was in a tone of like, what do you think? And if I said yes he would have considered going. I just froze and didn’t know what to say because I was in shock. All of sudden I felt like I was being abandoned to hold down all the kids 1 week after birth. He quickly said “oh I’m not gonna go” after seeing my reaction, but to even bring it up I felt was so inappropriate.

Second thing today is I’m sitting here feeding the baby and all of a sudden he goes “whoa, why did we charge $xxxxx to our credit card last month??” Like seriously asking me the question. He says this exact sentence almost every month for the last year and he is a finance guy. He manages our bills and I am a SAHM. Again I am still 1 week postpartum. I replied why are you asking me? Like what am I supposed to do here? He gets pissed and walks out.

I don’t shop, I am frugal, I buy groceries and the kids clothes. Asking this question every month isn’t helping and I definitely cannot deal with this right now.

I’m sitting here just pissed off. Am I overreacting?
