Uhm what do I do NOW

My crush now likes me and I don’t know what to do.He is showing affection with NO limitations. He is pitting his arm around me and walking me to class and everything. I know that #confidence is a good thing... but I’m #CONFUSED! At first he said he didn’t like me, but now he is hugging me?!? UGH! Guys are complicated! I need advice! I mean I kinda enjoy what’s happening but at the same time I don’t even know what’s happening! Please help!
