<human>: Hey, we've been dating for a year and a couple months, and we got into a huge fight a few days ago. He called me controlling and a lot of mean stuff, and broke up with me. Today I left a really sweet long apology letter at his door for Valentines day, and he still hasn't texted me or anything. I'm getting worried that he doesn't want to stay with me.

The reason we had our fight is that he went to the mall with one of his friends, her boyfriend, and her friend. Her friend is a girl, it was almost like a double date. He didn't even tell me that her friend was a girl, I had to find out from his friends Instagram post. And I confronted him about it, he admitted to it, and I just kinda said you know you're not allowed doing this again, and he said that I'm controlling and stuff, and whenever he calls me that it really pisses me off, and I ended up hitting him sort of. That is a completely rare occurrence though and I was just frustrated that he took me caring for him as being controlling. He said he was breaking up with me then, and I've sent several texts & calls since and he hasn't responded, I left the letter earlier today and still no response. 

I'm starting to feel depressed, I really don't want to break up and he means literally everything to me. What can I do without seeming crazy? :/ I've sent over 5 texts, a few calls, and now a letter and I'm trying to just wait until he responds to me for now, but it doesn't seem like that's happening.Help :( Sorry if I have crappy grammar btw, it's like 3AM.

Could you distill the essence of the text into 1-3 sentences?
<bot>: My boyfriend of over a year, wants to break up with me because he says I'm controlling. I want to stay together.
