Haven't heard from him in a week, should I text him?

Anonymous
So my more then a friend guy went away to see some family in another state and the last time I got a text from him was when he almost arrived(he drove there-it's a 16hr dr) He's very family oriented so I wasn't expecting to hear from him too often.Needless to say I haven't heard from him at all! Two days later I sent him a text saying hoping all was well and to text me when he could; he never responded to that text and that was a week ago. I know he's not back since we work at the same department, but I'm just wondering if I should wait for him to text or if I should send him another one?
