Don't tell her if you want her.<br />
Just do something to grow your relationship with her, like go for a coffee.<br />
A lot of men don't know that women actually really like MEN, and being the MAN is about making things happen. You are the one that has to say what you want. And she is the one that is going to miss out if she plays silly girl games. Enjoy, trust that you have a right to any woman you want.
Just ask her out!
Just be honest and tell her you'd like to spend time with her the next time you go to the other side of the frickin world.
tell her or you'll regret it for your whole life. if you let fear get in the way it will begin to take over. don't let it start now or it will just get easier to be afraid. make it easier to be stronger. it is always hard at first. if she likes you back and you never say, you may lose a great time of life. risk it. if she doesn't you have started your way on a path that will bring more yields in the future. its not the end just a new beginning whether she says yes or no but its just an end if you do not bother. so get her, take her, live, love, go on and god speed! lol.
all the best to you. the words may seem hard because there never are any right ones in a manner of speaking. jut make them nice words affectionate and passionate. ask her questions. i think something as simple as being interested in her day will suit fine. as shes talking relax and consider what you want to tell her. listening to her voice as shes telling you how she is i hope will help center your thoughts. i dont actually know much about relationships so i hope this all makes it come together well. honestly i find it riveting and would feel good if you win her heart. i dunno why. anyways good luck man!
In person would be prudent...
Your relationship can build via pen pal, but really , what are you hoping to achieve without being in the flesh.
with a suicide pact like all great romances
O.o umm no, just no
i was merely offering up a suggestion ;)
