idk what i should do!! help!

so there’s this guy and like three months ago we were in the same school project thing and after school we would work on it and after we were done he would pick me up and run and take my phone and look through my snapchat and was being super flirty with me but after our project was done we didn’t really talk anymore but we still snapped and lately we’ve been talking on snap a lot and sometimes talking at school and i’ve always had a crush on him since the first day of sophomore year so i just decided to tell him that i kinda like him over snap and he told me that “i guess i’m into you too” and he told me that he wanted to finish off the school year first before getting into anything and i was okay with that but then two days later there was a school shooting at his middle school and he was really sad and i want to like be there for him but he’s stopped snap chatting me and idk what to do. also i feel kinda scared that he actually doesn’t like me
