My mate's Canadian girlfriend hates me too, we should form a support group.
She's not an underwear model though, she's a social worker which you'll probably agree is marginally less sexy.
Anyway, either:
1) She hates you because she's an utter cokehead
2) She acts like she hates you because she fancies you
and gets off on the conflict
In conclusion, you should definitely try and nail this bolshy mountain yank.
Either 2) proves to be correct in which case you get to have manic coke fuelled sex with a Canadian underwear model.
or…
1) In which case, what do you care? She hates you anyway.
