<human>: This really happened yesterday. So here's some backstory: I've been dating this girl that we are going to call Jamie for 3 months (she is a year older than me). It has been going well all things considered: no fighting, generally similar in lots of ways, found out we had lots more in common than we originally thought, etc. There is this extremely good friend I have who we are going to name Blaire. We are pretty much inseparable, and I had learned that I didn't like Blaire when I took her to homecoming last year. Despite this, we still remained extremely good friends who have lots of classes in common, causing Jamie to be a little concerned from the beginning.

Last night, Jamie and I were Skyping. My computer ran out of battery around 11:00, so we decided to continue a call on my phone. We were talking about college and about we are looking into different futures. She makes me promise to her that my decision on colleges won't be swayed by her, and I decide after a long time of thinking to finally submitting to her will and agreeing to go our separate ways after high school. It is 12 now, I am tired as all hell. I was the type of tired that can only be described as you don't even know what you are saying half of the time. Anyway, this is relevant because I thought I said one thing, and it turned out to be another. So, what I thought I had said was "I love you Jamie. I cannot ever imagine a life without you, Jamie. This last year of high school just couldn't ever be the same without you, Jamie." The thing is, I didn't say Jamie. I said Blaire.

Horrified, I try to say sorry and all Jamie does is try to laugh it off. I realized how bad the thing was I did though, so she stops wearing the mask and today she is completely cold. I asked her about an hour ago if she wanted to break up because I clearly could see her wanting to, but just not wanting to say it, and she agreed.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: While tired as fuck, I said I love you to Blaire and not Jamie, which led to us breaking up today...
