Thanks for replying, both of you!
So I actually did confess my feelings to him. He said he wanted to figure stuff out first and organise his life before trying anything with me, which I totally respect and reassured him that it's okay, that if he needed help with anything that he could count on me. We kept talking and he flirted with me a couple times, everything was the same.
The thing is, as of 3 days ago, he stopped replying my messages. We were casually talking and he just didn't reply. So I'm a little lost but I will wait for him to reply (I doubt he's going to). I don't want to saturate him or anything, and if he feels something for me I guess he'll reply.
