<human>: Can you give me a shortened version of the text?

My friend and I have been close for about a year or so. Recently, I THINK** we had a falling out. I said something kind of snippy...but had no idea it would be that big of a deal...

A couple days later I felt bad because we weren't talking so I wanted to apologize. I started off by saying "hey" and he saw my message and didn't respond. 2 weeks now, and we still haven't spoke a word to each other when we used to talk every day. I try to reach out again but he makes it obvious that he's ignoring me too. 

I'm really not sure what to do at this point. I've basically been shoving it under the rug, like "oh well, there goes a friend... i don't care, he's the one being a jerk" but I think deep down that just an excuse because I'm so afraid of confronting him and asking what's wrong etc. At this point I'd rather lose him as a friend then to hear him say how he hates me or something. 

Is there something wrong with me? Do you guys think I should really do something? I just don't know. and I don't know if its worth confronting him because it feels a bit unfair to me as I'm not even sure why he's SO mad to be ignoring me for 2 weeks?
<bot>: friend is super mad at me for GOD knows what and I'm not sure if its worth confronting him about it because I am a very NON-confrontational and sensitive person
