First off, your still experiencing so called culture shocks, and inclining
toward ppl around you. She just happens to be the one close to you now.
Those things you mentioned doing together are the common things me and my
besties, guys or gals, usually doing.
There is a cure. Let your feeling about her go, heal yourself, and go out
have a life. Eventually you will find someone who will not only return your
feelings but who will treasure you. You can live without her. It may not
feel like it at first...but you have already been. If you want to keep the
distances try to stick to your words. It will help with feelings for her to
subside. It's an inner battle. Chin up, it will hurt for a while, but moving
on will hurt you much less in the long run then holding out for someone who
doesn't return your feelings and doesn't appear to have romantic feelings
for you at all.
If I sound rude or harsh that isn't my intention, I'm laying the facts as I
see them out for you to also see them. I hope this work out for you.
P.S. If you really wanna know how she feels, stop guessing, GO ASK HER.
