<human>: So things were going great up until a week or two ago. We have met each others parents, said I love you, and done all the things "serious" couples do, short of living with each other. I did not push for any of these things, if anything it was him suggesting these steps forward, and he seemed happy with them while they happened.

About a week ago, he suddenly stopped talking to me out of the blue, and yesterday he broke up with me. According to him, it was because things was going so well that it was headed in a very serious direction, which he was not ready for. I don't understand because it seemed like we were both really happy all along the way.

To me, this seems like a blatant lie. Why would you break up with someone because things are going well? Has anyone ever broken up with someone for this reason? If so, could you give me some insight into this?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: boyfriend broke up with me because things were too serious, when he was the one who made them serious. Has anyone ever done this?
