advice needed!!!

ok ladies i need some advise. i just got out of a 6 month relationship, which isn't that long until you consider that factor of me liking him 3 months before that. he was the best boyfriend i've ever had and i thought he really liked me. he was a very sappy person especially when we hung out. yesterday i got 100% sister zoned. "i love you like a sister, not a girlfriend, i still love to be your best friend like we were before all this, but i'm sorry." i don't know who texts there sister every morning saying "good morning beautiful" and tells them how amazing and perfect they are, so now i'm pretty hurt, but on top of that i was told that he broke up with me because i was telling personal things about him to his best friend (which i haven't been!) so i lashed out on his best friend, who isn't the most forgiving of all people, so i lost an amazing guy, and an amazing friend, HELP!
