does my crush like me back?...

I think your best bet is to talk to him, get to know him a bit আরো and then ask him if he likes you.
If আপনি dont want to do the asking then get a friend to ask him if he likes you.
If seems like he likes আপনি back but asking him is your best option. :)
Hope that helps!
Good luck and I hope it all works out for ya! :)
