<human>: On day 4 now of cold turkey and my spirit is starting to lift. Had been dating girlfriend for about 4 months and I feel like it was a short and intense relationship. It was exclusive. In the last two months we spent nearly every day together (I even spent a lot of time with her family, too), but I knew from the start that she had never had been on her own, single, and taken time to travel and discover herself. She had also been in two relationships back2back prior to mine, so I knew it would catch up eventually.

She was going to finally travel to another country, and we had a couple discussions whether we needed to separate. I was then under the impression that we would continue and she was happy with things. However, a week before she was to leave I said the "L" word (in a happy moment while drunk, oops) and the next day she said we're on different pages. After 20 minutes of talking, I said I couldn't be friends and needed to go, she gave me a very long hug, and I walked out.

I haven't seen, messaged, or made any contact, and now I'm on day 4. The days are a lot better, though my mind still wanders at night. Has anyone experienced such a quick breakup after seeing each other so frequently? Is it weird that I feel like it ended so quickly and I've been able to accept it?

Can you summarize the given text in a few sentences?
<bot>: Ended 4 month relationship cold turkey. Starting to feel better, but does it really happen that quickly? Why does the whole thing feel surreal?
