Would a guy travel out of state just to see you if he wasn't looking for something serious with you?

We have tons of mutual friends from our hometown, and we've talked over the phone for over a month, and now he's coming down, on his birthday, to spend it with me... but I'm not sure a guys capable of doing this just to get some. (W/ that said he is attractive and has his stuff together

Ok so its two days before he's coming down here and he's barely talked to me all day because he's "addicted to the game on his phone"... should I take this as a red flag, or nothing of significance?
