In an almost tv-like situation: a girl I like told me she likes men with facial hair. So here we are, exactly two weeks in and I'm not sure if I can keep this up.

Is this a pack it up and try again in a couple of years or is there potential?
You can't give up after only two weeks.  You need to plan on at least two or three months.  I think you can do something but also consider that blond beards and 'staches don't initially show as readily as darker facial hair.
