About a year ago, I went on a few dates with "Daniel." I had a great time and was interested in what might come of it, but after those initial few dates, he started to fade away: He took longer to answer calls and texts, conspicuously left town right before Valentine's Day, became markedly less flirty when we did talk. I chalked it up to loss of interest and was unsurprised when I stopped hearing from him altogether.
About a month later, he got in touch with me to let me know he felt bad about ghosting me, and that he had done so because things had gotten serious with someone else he had started dating around the same time, "Kate." At this point, he was happily in a relationship with her, and said he wished me well.
Last week, he reached out to me on Facebook wanting to talk about [something involving a mutual interest of ours], and we met for coffee -- not a date, in my understanding. There, I found out that he has since broken up with Kate. He didn't immediately ask me out on an actual date, but he did so last night -- and now I owe him a response.
On the one hand, I still really like this guy as a person; all the things that attracted me to him last year are still true, and I'm still single. On the other hand, it stings that -- oversimplification alert -- something about Kate caused him to choose her over me when we had both begun dating him at the same time.
I owe him a response.とoversimplification alertの意味を教えください。よろしくお願いします
