I understand what it is, just not why it is.

For me, depends entirely on what her relationship is with her ex. I'd imagine it would be the same with guys: if you're not over your ex, obviously, it'd have to be a pretty shitty friend who went out and banged them when you were still hurt.
Other than that, it's kind of a possessive thing. Like, you may be broken up, but your ex still sort of feels like your ex. To put it in a better light, you share a history with your ex. You felt a connection to them. And sometimes, even when you're over them, it's hard to see them have a new connection with someone so close to you.
And sometimes, friends just vow not to date their friends' exes for a variety of reasons, one being that the ex in question has already been deemed unacceptable. Haha.
