Is he distant?

My husband is out of town for work, he has been gone since Monday night. He is with a few co workers and they have been super busy trying to get the job finished to come home. They went out for drinks tonight and they’re hanging out in their hotel rooms together now. My husband hasn’t initiated any type of conversation with me or our son since he’s been gone. I’m trying to look at it like he really needed some time for himself, and he has been crazy busy, but I can’t help but feel sad like he isn’t thinking of us at all. Would you feel kind of sad? Or just not care? Im happy he is hanging with his coworkers, they got some beers and dinner. Just wish he would send a text or something 😕
