Am I being petty or am I right to be kind of upset

Husband took off to his best friends bachelor party in anothe state. Hes been gone for three days and I've been taking care of our two babies on my own. We have had minimal contact since he left (maybe one text a day) Every time I text asking if he's having fun etc he just says he's having so much fun but has not once asked how me and the kids are doing. I keep having to initiate the texts to get any contact at all and he promised when he left he would check in often since its Vegas and I know it's sketchy. Why wouldn't he care to ask about his kids? I feel really weird about how stand offish he's being😩 would be you be upset or am I crazy?
