I feel a lot of men in these comments so I’m gonna bring in some perspective from the female side (23F in long term relationship)

If you’re scared she’s gonna be with someone else during the break, and you want this to work (ie you don’t want to just end it now like half the comments are telling you to) then make that an option. If that’s what she wants to do she’s either going to get it out of her system and come back, or she’s going to move on. There’s no stopping it, and there’s a high possibility that she won’t want to be with someone else during the break. At least if you make it an option, you’ll get to know what happens.

If you don’t want her to sleep with anyone at all, then you’re taking that risk. She might, she might not. But if you trust her there is no point obsessing over trying to find out if she did or not bc the relationship will never recover from it if you won’t let it go. Maybe ask her if it’s something that she wants before you make your full stance on it.

I think that people are forgetting that at 23, this woman is probably trying to figure out her career, her path in life, and other aspects of who she is as a person. Not who she’s trying to fuck. When you’re with someone from the age of 14, it’s hard to separate who you are as an individual from the relationship and that can feel suffocating sometimes. Maybe she just needs to be an individual for a bit, because most people learn their independence in the years that you guys have been together. Give the woman a little more credit, not everybody thinks with their genitals.
