Would you be wary?

My coworker asked me out but told me he was kinda considering another girl too. He then spoke about marriage in general, kept asking me to introduce him to my family/friends, said he was moving states and tried convincing me to move somewhere closer to his house. He's honest and not the type to lead people on, but I'm not sure why he's saying all this especially coz he's also considering another girl.

Is he just infatuated? Or dodgy?
