Are you physically attracted to her in any way?
^ I was wondering that as well. So, Shaz.........do you find this girl to be pretty enough at least for your liking?
Do reflect over the points that have been made in your thread. If you were to move to Pakistan.........you'd appear awkward to the natives of the country as you try to adjust to life there. So.......try helping her adjust and talk to her about your concerns.
Keep in mind that language has it's own style across cultures. It's hard to explain. For example.......western humor/teasing is different from desi humor. Perhaps desi humor might seem more harsh. Similarly mannerisms and the nuances of casual language differ from culture to culture. For example....in Western culture.......it's considered RUDE to stare. In DESI culture......people have lax views about staring and it's not such a big deal.
^Keeping this in mind.........perhaps the things that she says....and the way that she says them.......are simply out of place in the UK because of a change in the cultural environment. Maybe she's not intending to be rude when she teases you about your hair. It could possibly be a juvenile attempt at flirting.
