Hey all! first time poster here

States: Body Fat 15%, Height 6", Weight: 175; Lifts:3-5 a week, hoping to increase it to daily but because of work it is hard

Reading: Have read NNMNG, that's about it

Finanaces: about to graduate next semester, no job promised yet will see in my internship starting in a few weeks; currently work retail, no debt

Spiritual: I'd say 7/10, I lead bible ministry on campus and with my circle of friends in my community so I am a leader in terms of my social circle; I have prayer and quite time every day, average of 30 minutes to an hour; I have a handful of scripture memorized, mainly NT

Mission: I know I want to be a leader in some way in the church (a pastor most likely) just not sure how or where at the moment ​

Here's my issue, Girlfriend is going overseas to study abroad for 2 weeks, I heard stories of GF's doing crazy things over there and most end up cheating on their BF's, some of my bro's says it happens, I am a little worried as my gf is 19 (I''m 22) and I'm her first everything, I don't know if she can overcome being tempted in that scenario, she's very outgoing and at times naive and cannot notice if guys are flirting with her, tbh, I fear that she may make a "mistake" because she's inexperienced, is this my insecurity speaking? Other then her being really sociable She hasn't done anything that would cause me to not trust her, she's honest and a God fearing women, doesn't party, drink, virgin etc; but will that change if she's in a whole new environment? am I being cynical?

What concerns me is that she wants to go on a few study abroad trips at this point in our relationship (one year)...I even turned down going abroad for her (she said we should go together next year when I have enough funds, to be fair my trip was just a leisurely trip, not a study abroad) She did say she understands and that I can go abroad without her after explaining I felt miffed about turning down my chance to go. I just find that a bit strange if you're in a serious relationship you would take all the chances you can to study abroad, in her defense she says its for her studies, for her to learn more in her field ; we have even made plans for engagement (in the upcoming year) (also she was home school for most, not all for her education)

My gut feeling is telling me something may happen, but I don't find any evidence of that being a possibility, only weird thing is that she wants to go on these trips and she hasn't really asked me how I feel about her going abroad. (EDIT: she has one time said she thought of ways of me coming along but said that it wouldn't be wise for me financially, she has a point as I don't have enough money to go with her, she's on a scholarship)

Also the fact that most of her classmates that are going are guys, one female acquaintance of her may go but that’s unsure, so 60% she will be the only female (disregarding faculty of course, one female teacher is also going, but I’m talking among fellow peers)

If I’m overthinking, please slap some sense into me fellow brothers, I’m not usually like this I just feel weird thats all

TL;DR, Girlfriend wants to go on a few study abroads trips, both lasting 2 weeks, fear that she might succumb to temptation because its her first time in that environment (no accountability), am I worrying for nothing, is this insecurity?
