She freaked out and ran away because of a kiss on the cheek? Not even a french kiss? Hard to understand.
However, if this freaks you out never go near a male French (or Italian) as this is a common welcome and goodbye, in business and private relations.

If someone has such a problem adjusting to local culture better learn rapidly to adjust or stay at home.

By the way: I (male) made the experience that I actually offended french girls because I did *not* kiss them on the cheek as a welcome.
