<human>: This girl I've been seeing the last month and a half or so isn't ready for a relationship because she only recently got out of a long one. I'm fine with that, I'm comfortable with what we have now, because she told me that given enough time, I do have a shot with her in the future.

We're in different countries for Christmas break for about 3 weeks. I won't be able to text or see her. We've been emailing a bit, but it still sucks not to be able to talk to her as much as I want. I want us to still be in the same place after we come back, but I'm having trouble thinking about all of this. I'm worried the time apart will give her time to think, and that she may come to the conclusion that we shouldn't ever be together. I don't know why, but I'm having to convince myself she won't hook up with other guys while she's back home and I'm away. There have been no signs that she's going to do that, she actually gave me her underwear with her perfume on it before I left for break, which I think is a pretty good sign for me. I know she lives in a fairly small town and that she could run into her ex. I know they were best friends before dating, but I think she told me she wasn't planning to hang out with him over break, but it's still not something that I can control so it sucks to think they could hang out and she could start having feelings for him again.

I'm hoping the time apart actually makes her realize she misses me and that there is something there. Is there any advice to how I can go about thinking she won't be hooking up with other guys or anything involving her ex? I know it sounds stupid and insecure, but something similar happened to me before where a girl said we'd be good after a break but it didn't work out. Are there any positives I should focus on for this time apart? I'm trying to convince myself there is no reason to think she'd actually hook up with other guys since there are no signs, and that I'm just overreacting.

Can you summarize the given text in a few sentences?
<bot>: spending time apart, need help thinking that this girl won't hook up with other guys or anything remotely close to it.
