This did happen to me, but I didn't know enough to understand what it was, and I did what everyone else thought I should do (leave for the new guy) instead of what I really wanted to do.
I did this quite a bit in my late teens/early 20s. There are a couple of relationships that I left that still kinda sting to think about.
We call this serial monogamy, so you might try searching for that.
