Boyfriend doesn’t text me for hours

My boyfriend goes to a diff college and sometimes he goes out to parties or day parties. Usually he would Text me during the day. But lately every weekend he wouldn’t text me for hours during these day parties. I’m hurt by it but I don’t want to seem like a girlfriend that needs 24/7 attention and for him not to hangout. Idk what to do. We’ve been together for 2 years now and this is very recent
