Women or Business?

So recently more and more i found myself deciding between keeping my GF happy or getting work done. I'm not sure really what to do anymore, but its getting REALLY frustrating and im not only taking it out on her, but my friends too.

I have my own company that i have been working day and night for the past few months to make successful and to this day is doing better than I would of thought. there is so much time needed per day, each day, including the weekends, however I cant put in 5 hours a day and forget the biz until the next morning when i wake up like she can (shes a teacher).

Anyway, i tried talking to her this weekend and she just doesnt get it and im not sure what to do. she dosent quiet grasp that I need to put in a ton of time to get this to move along quickly, then once it does I can pull back a bit and go along for the ride (for say).

So im stuck between a rock and a hard place. do i tell her to take a hike (we've been togther for 5 1/2 years) or just keep dealing with the day in day out frustration and BS? Im not trying to be a jerk when i say this, but I will not give up what I have done till now. I have worked my ass off to get where Im at, and what i have accomplished. So, the decision has to be try and explain it to her again in another way, or buy her some luggage
