So im a junior and this sophomore boy Josh was talking to for about 5 weeks( he never commited to me) is mad at me now because i believed this guy in his grade over him. So this guy told me that Josh dont want me and he been going with this other girl at the time me and him kissed. And i believed him because josh never messages me first, he always ends the conversation and he has alot of girls on his facebook page and flirts with hella girls (thats y i unfriended him from facebook because his page makes me soo mad!) but anyway after the guy told me that i cursed josh out then i found out from his bestfriend and josh that what that guy said wasnt true , and josh says he doesnt know if he wants to keep talking to me cause i believed that guy over him. And his good friend Andrew messaged me on facebook and told me the same thing, So i apologized two days ago and asked him for a second chance and he never replied but it said he seen the message! Im crying my eyes out right now cause i kissed him about to weeks ago, he doesnt want me now and i feel really bad, so yesterday he messaged me asking why i unfriended him from fb and i said because of that guy who was lying and i asked him did he want me to tell him wat he said and for his new number and it said seen but he aint reply... Now i know he really hates me but the main reason why i unfriened him is because all them girls on his page and stuff and it hurts me when i see that.. But i didnt want to tell josh that. Sooo now he hates me what should i message him now, i really like him and still want to be cool, how should i start the message off or what should i say?
