I NEED HELP!! :(

Okay, so i went out with this really sweet guy because he was practically begging me for a whole month. So i finally a dit yes, and i totally fell for him. He just would tell me the sweetest things in the world. But 2 days later he broke up with me saying, "I have to break up with toi cuz im in l’amour with someone else." i was completely shocked to say the least. The suivant jour my friend told me who it was he "loved"... it was my best friend. She's 2 years older than he is, so she isn't interested in him, but it still made me pretty mad. We spent a whole mois practically not talking. he kept trying to say sorry, but i just ignored him. we started talking again last month, and he wants me back... but i dont know if i should give him another chance... i need help..

WHAT SHOULD I DO??!?!?!?!?!?!?!
