More teenage mellowdrama.....?

i am 16 years old. when i was 13, i told my best friend in the world that i was bi (i thought he would be a bit more comfortable with that rather than just telling him i was gay, don't ask me why.) to which he replied, "me too." over the next couple of months i found myself more and more attracted to him, both emotionally and sexually, so on the last day of school i invited him to spend the weekend at my dads house with me. We were hanging out like we always did, and suddenly before i even knew what i was saying i offered to give him oral sex. He enthusiastically agreed. so we went out to the woods behind my dads house, and after about 30 seconds, he says he wants to stop. i asked him why, he said he was straight. i stood up, and now he looks as if he is furious at me. he starts to shout at me and acts as if he genuinely wants to fight me. We haven't said more than two words to one another since and now every time i think about him i feel depressed, often times going into my room and crying. Now my question is this, do i cry because i love him, or do i cry because i lost a good friend?
