My girlfriend and I disagree on my living situation. Who is right here?

I just started dating my girlfriend 2 months ago. She has an apartment in a nice part of town. I live out of a hotel room by choice. I do not see the point in paying rent AND utilities when I can save and buy a home. What I pay at the hotel is equivalent to rent in my area, but without utilities added. My girlfriend believes I need to get an apartment at my age. The hotel has everything I need.

To clarify my rent situation, I pay $320 per week, which is $1280 per month, with no extra for utilities.

I live near Nashville, where the average rent is $1300 easily, with $1100 being the BARE MINIMUM to avoid the ghetto. $1100 plus utilities in Nashville can add up to $1700-$1800, or even $2000 in the winter. NES, Nashville's electric service, is excessively expensive, as are all the utility districts within an hour of Nashville.
