If your new love interest is in it for a long-term thing -- and you're not -- they might feel worse for you letting it go on for so long rather than being up front about it at first.
Especially at the beginning of an overseas adventure, it can be easy to make a new fling your everything immediately.
You wouldn't want someone to use you just for English practice, so think about how you would feel if it was the other way around.
I've even had guys ask me, "Why should I even go out with you?
You're just temporary." Ouch, but point well-taken.
Likewise, it can be just as easy to fall for a friend and not bother to continue to develop a separate social life.
Make sure you have a distinct social circle so if things go south, you aren't alone and having to make a tough choice between all of your new friends or your former love interest.
