Charlie, there really is no problem, if you think about it. She can't reciprocate, so you just need to move on and be realistic about the situation. You may also want to consider the possibility that the reason you're in love with her is that she's unavailable, and therefore safe. We're often attracted to what we can't have but ultimately, this leads to loneliness and frustration. Please consider reaching out to a girl who is more attainable as this one is just "the impossible dream."
