So, there’s this guy

So I met this guy on reddit a couple of weeks ago (I know not a long time but here we are) I have a crush on him, we spoke every day and threw in the odd compliment. I’m unsure if he had a crush on me but anyway, a couple of days ago there was radio silence. I didn’t get a reply until the next day which was very brief saying he’ll explain later and apologies. I replied, 3 days ago and still haven’t got a response. Now I know he’s active because he has seen my Snapchat stories and his snapscore goes up?¿ what does this mean
