So i finally tell the truth and hurt him now i feel like crap..?

so i lied to him about my age.. and i truly loved him, and i decieded no more lies, im gonna tell him, so i told him, and he got so angury, i werent expecting it i thought if he loved me.. he'd understand, but he freaked out, and i was an emotional wreck, i no it was wrong, and then he was like, 'dont worry its cool, keep your chin up, i accept you.. see you around abs...' then im being accused of being a compulsive liar, as my ex is his bestfriend, and claims he doesnt no me, when i told him me and him dated.. its just all crumbling down on me, i feel so numb, i want to sort it out, but he dont believe me.. :'(
