Boyfriend or New Fling?

I have been in a really great relationship with my current boyfriend for 5 years. Ive always been looking out for other options though... I dont know why. Right now I am in Germany for the summer (away from my BF), and I think I am falling for someone here. I dont really have any friends here because its a small town and I am a foreigner, and this other guy is really the only friend I have made so far. He is really sweet, fun, a refugee from Syria, and REALLY really cute. I cant stop thinking about him... Plus he wants to hang out more and more (as do I)
