It's just not funny

Let me start with my husband is a good husband, he's supportive and and overall good. He's not always been like this we've been married 7 years and it took a huge chunk of the 7 years to get to a good place. Anyway, I've had our 2 boys for 2 full days and 2 full evenings, ages 4 and 4 months, as he's been working and had an event with friends, absolutely no problem I knew these things were coming up I was mentally prepared. Obviously, it was hard-working solo but it happens. Yesterday he comes home and I was ready to hand both boys over so I could get some rest. Our 4 year old was waiting for him etc. He asked him how he was doing etc. Then came to me and sarcastically said "how was your day" almost like he was saying "oh I better ask you too" he was trying to be funny. But it was just insensitive, I got so upset because all I wanted was to feel like he understood how hard it had been. He apologised and said it was insensitive etc. But I'm still so annoyed because, why?? And then in the evening he scrolled on his phone and went to sleep without saying a word.
