High school + guy + what do I do

Hey guys, I’m a senior and basically there’s this guy that I’ve liked on and off for three years and I’m pretty sure he’s like me as well for the past three years. We’re seniors now and we both got into college and he basically texted my best friend asking you know if I’m interested in him. She responded with yes immediately, so should: I let things play out OR should I stop wasting time and go and talk to him OR should I ignore the entjre situation
