I can't figure out if you think you're showing off by having a goth girlfriend, or if you actually refer to her as that to others instead of, you know, her name.
As others said - that might be why you're fighting.
As everyone else has said, what does being "goth" have anything to do with it? When you say goth, all you're causing is people to generalize what her personality is and picture what she wears. You're putting a label on her and assuming that when we hear the term goth we know exactly who she is.
Not to mention, no one can really give steady advice if we don't know what the problem actually is.
