Should I just let it go or should I say something

So obviously everyone knows today is Christmas for Hispanics and I'm just so hurt because the father of my two girls decided to take off and go see his family an hour away and leave his daughters and I alone on Christmas. We just had our second daughter on Dec 2 via c section and we already have a 1 year old together and I still haven't gotten the all clear to be carrying her yet should I be pissed he took off or should I just let it go?? Since tomorrow is technically Christmas for him
