<human>: Can you provide a brief overview of the text?

My boyfriend of 6 months and I have been on and off. This time its off for good, is what it seems like. During this breakup process, my ex went off telling everyone we know that I was a liar, and thats all I do...mind you, he says this stuff loud enough that our whole class is eavsdropping on him.
We are both 16, btw.

Its like he purposefully brings up topics of conversations that piss me off with the people around us, only when Im around.
I overhear him talking about how hes going to hang out with a girl he knows this weekend, and he makes it obvious he wants me to hear.
He took out a letter I wrote him that he had on his binder, and replaced it with a picture of his name in bubble letters that his ex drew for him.

He will text me about personal things in his life that only I know about, and I tell him I hope they turn out for the best and that he ends up happy, and he accuses me of acting fake, &wants me to "leave him the fuck alone." So I do. I dont talk to him or text him, but lately he's texting me, about the stuff that goes on that only I know about him.
He said last week that these 6months have been a waste, that he wont have an impression of me at all because from that conversation on, he wont think of me again...that I screwed him over more than anyone else & that Im the reason he will never trust girls again.
So I am leaving him alone, but he always talks to me first. Whats up with this?

Somehow, I still love him...I think of all the amazing memories we created and everything we came through together, and I cry...wondering why and how it ends like this.
But I'm sick of his shit, and I'm trying to convince myself not to care about him, not to love him, not to wonder what he's doing or what his opinions are of me.
How do I do it? I really need help :/ But please, be kind...I know we're 16, but please dont be rude or call  him an asshole...serious advice only please.
