<human>: Can you summarize the given text in a few sentences?

I am an avid skier, my gf lives in another country about 5 hours away. I have spent the last few weekends skiing and have gone way over my budget for this month. This weekend just opened up on my end that it would be a possibility for me to go see her. I told her I was quite tired and didn't have the budget ( it would cost around 200 $ to go there) She replied very evenly but seemed to get more heated and came out saying that she should be as important to me as skiing is as I already spent so much money on that. 

She is extremely important to me, but I don't think it is fair to equate a person to an activity. I believe we both need to be able to be happy on our own accord doing the things we love. Obviously there are sacrifices to be made, and they will happen. However in this instance I've already spent the money, I am not doing more skiing this coming weekend and I don't know how to tell her that I don't think it is fair to equate her, someone I share my life with to something I do in my life. I'm just grumpy now and don't know how to say this without coming out as a dickwad, or maybe wrong.
<bot>: How do I tell my gf I'm not coming to visit her and she shouldn't compare herself to my hobbies without hurting her.
