<human>: Can you provide a brief overview of the text?

Me: M23, with GF(F20) of seven months.

She's in Brazil for January, then back in the US for two months, then returning to Brazil for her entire spring semester, so we're effectively long distance right now.

She told me a week or so ago that she had a crush on someone[M...2x?] she'd met there, and I didn't think too much of it because who doesn't get crushes, especially when relationships go long distance? 

Fast forward until now, when she admitted that she told him that she liked him, and that the feelings were mutual. They ended up talking and given his relationship with his ex, and my GF's relationship with me, determined that nothing was going to come of it, but that they still want to keep in touch. 

I'm hurt that they want to keep talking. Especially when she still admits to liking him, yet still claims to love me more than anything else and that this whole episode is making her realize "just how lucky she is." Am I justified in requesting that she keep her distance? She's already gone to sleep so I'll ask her the next time I get to talk.
<bot>: GF wants to keep in touch with a mutual crush when they've determined that it wouldn't work, I'm offended and want her to keep her distance. Justified?
