<human>: My ex boyfriend has spent about $8,000 to $9,000 dollars on gifts and surprises for me during our 1 year together. Every time we go out, he buys me clothes, shoes, chocolate, jewelry, even though I never ask him for anything. He comes from a middle class family like me, so it's not like he has money to throw around and I'm not used to having so many nice things that I don't know what to do with them. He even hired a guy once to write me a song. A month ago, I stopped him from buying $300 pair of heels for me because I can't imagine when I would wear it.

Then yesterday, we got in a big fight and instead of us both calming down and apologizing to each other after the fight like we do most other times, he said he has had enough and wanted to break up. He said he didn't want me anymore and that I was just taking up space. I told him okay and left. Today he called me twice but didn't say anything, and he hung up before I could say anything. A friend said my boyfriend told him that he's sad and misses me, and that he wants me to go back home. But when I called my boyfriend, he didn't even pick up. What's going on?

<bot>: My boyfriend spent a lot of money, time, and effort on me, but now wants to break up. Will someone please explain what's going on through his head?
