I am now certain that he is keeping his options open.
why is he still active on the website?
you've already answered your own question
his options are open
3 to 4 months in a real-life, in-person, local dating relationship would be very soon to be discussing future plans
it is crazily soon to be discussing/considering the future in an online/long-distance relationship
you're not even really dating this guy
If you like him, stay in touch but confirm that both of you are free to see others at this point.
Date other people locally, visit the guy if you want, keep your own options open and active.
