UM IS HE A FUCK BOY OR DID I FUCK UP

Okay, there's this guy, let's call him M.
Okay I like M, I don't know if he likes me back but I think I fucked up pretty bad, I was in a super bad mood and texting M and I just hated it when he left me on read so I sent him a picture of me and my best friend flipping him off, calling him a bitch, and using numerous cuss words AND to make it worse, I said it was on accident which I totally forgot is like a 2 step process. So now, he won't talk to me but he's talking to other girls, like ALOT. We haven't talked, looked at, stood, sat, or even breathed near each other, so basically we've been avoiding each other for months! I want to talk to him and I'm apologizing like crazy but I don't wanna sound insane/crazy/mental/obsessed. I don't know what to do, I want us to talk again but how can I talk to him if we don't even talk anymore? I miss him!!
