he(21m) replied to my(22m) stories after almost 3 weeks of ghosting, should I answer?

r/

So I had been talking to this guy I matched on tinder for the last few months and felt like we had something really special going on. He’s from a different city and we never actually saw eachother irl, but had plans to do so during his holiday, as his brother lives near me.
A few weeks ago I was feeling really down about my looks so I acted a bit drier than usual and then he simply stopped texting me. After that, through his tweets (which he doesn’t know I have access to lol) it seemed like he had moved on and was only talking to 2 guys, one of which he actually posted on instagram (which, at least to me, feels like a pretty big move). To be completely honest, despite all that I still wish we could meet, even if it’d be casual…
With all this in mind, I accepted he was simply over me, but the odd thing is that he kept liking my stories, and today, 3 weeks of ghosting later, he ignored the previous unanswared messages and replied something funny to my pic, and now idk what to do.
Should I give him a taste of his own medicine and just ghost him or actually answer? and if I do, should I just act normally, be super dry or confront him? I’m super confused about my feelings, I’m angry but still very much into him, and just wish he had been honest instead of simply dropping off the face of the earth.

TL;DR: Guy I like had seemingly moved on but replied to my stories after weeks of ghosting, what should I do?
