<human>: Can you give me the gist of the text in a nutshell?

I'll give some backstory before asking for the actual advice. Me and my gf have only been dating for about a week. It'll be about 2 months when she leaves in early March then comes back in late May. I know it's not been long at all. We've known each other for about a year and have just gotten closer recently. We're both Spanish Education majors and I am doing all of my student teaching around our university while she is doing 10 weeks of her's here and 8 in Costa Rica as part of a teaching program for our university. This involves teaching a few classes and doing some volunteer work. She's a shy girl and I have no reason to think that she would cheat. My worries come from the fact that she will be abroad and that I have heard all kinds of stories, good and bad. She also likes to go out and drink but isn't really what you would call a "party girl." She also hates dancing/singing because she is too shy. 

Basically what I'm asking is, Should I be worried? I'm a very insecure person who probably worries way more than he should but the whole study abroad thing is killing me. I need advice.
<bot>: My gf is teaching abroad for 2 months and I don't know how worried I should be, if it all.
