I'm so guilty and confused

So recently, I have been chatting to 2 guy friends on facebook (they're safe - I've seen and met them before). I like one of them. A lot. But I did something so stupid that he probably hates my guts now. So my friend suggested that I told him. So she helped me and told him that I did. But he wasn't sure how to react. I immediatly felt embarrassed, thinking he rejected me, so for around 5-6 hours of chatting I was moaning about rejection and that I wanted to just die of embarrassment. He took it like a nice person, but I knew he got annoyed. So afterwards, because I panicked when he brought the topic up again, I said it was a joke. He shrugged it off and acted like he couldn't care less. For the past few weeks, it was like the conversation never happened, and I proceeded to act normally, as did he. So recently, he was posting and talking about random stuff, and I said to him he was being a weird guy. He got really annoyed at me, saying I was being aggressive over the last few weeks, and I didn't understand. I was like this with the other guy i was talking too, so didn't feel like I was singling him out. Then, suddenly, out of the blue, he brought the topic of my embarrassing conversation up, and we had a huge argumant about me annoying him and telling him lies. However, he shrugged it off, and the next day I didn't want to bother him by saying sorry and rebringing the topic up again. However, I felt guilty for wasting his time, and he got mean, saying I was a bitch and an attention seeker. Here, I completely crumbled, fighting not to cry as he talked about me wasting his time. What was the worst was that I ddin't know how to react when he said he didn't give a f*** about me. I cried myself to sleep once he said he was done. I felt incredibly guilty. The next day, I tried to look happy when I saw him at school. I tried to shrug off my depressed feelings, but I couldn't breath, sneaking at least 10 glances at him, only once did he look like the slightest bit sad. He's not said anything in a conversation, and the other guy tried to patch it up by joking around, and I managed to smile, but that's it. I talked to my friend about it, and she said I'm in love with him. I don't know whether I am, but I'm just scared the friendship we built up in the past through months will shatter because of the stupid conversation. Please help me by telling me whether I was right or wrong, and what I should do to make him like me... I'm broken.
