DID I CHEAT?????

Im 16 .I'm with my boyfriend 3 months , last weekend I went to a party with a few friends . I drank a lot of vodka and some other people's drinks . I was super drunk , this guy was literally all over me , he was up against a wall and I was right up against him he had is arms around me and his hands on my butt !! I kept trying to make out , but I was turning my head  . Our tongues touched for like 2 seconds but I pulled back . He kept saying my boyfriend wouldn't find out and stuff (that's what they all say ) !!! Then he tried to finger me , but I pulled his hands out . We didn't do anything sexual and just kinda touched our tongues . And he is a total jerk !!!! But does it count as cheating ? I love my boyfriends so much and I really really regret doing what I did, I cried for like 2 hours when I got back . I don't want to tell him because I  know he will break up with me . HELLLPPPPPPPPPPPPP
