what should i do?

so there is this boy in 10th grade that i've  been talking to and i really like him. He likes me back and we have hung out and kissed a few times but i'm in 8th grade. One of my friends has a class with him and they talk about me, he said he really likes me but it would be weird dating an eight grader. Also he has had sex before and i wouldn't be down to smash unless we had been dating for a while. what should i do?
