Is he into me or just being nice?

I met this guy a few weeks ago and we have been talking casually everyday, on Snapchat. He messaged me yesterday letting me know he wouldn’t be as active on Snapchat but to add him on Instagram. So I did and he followed me back. After that, I haven’t heard from him. Do you think he’s into me or maybe just a way to not talk anymore?
