<human>: Could you distill the essence of the text into 1-3 sentences?

Alright so my girlfriend and I have been together for a little over 5 Years, we've been together since freshman year of high school. Recently she's been acting super distant and giving me the cold shoulder. Yesterday I finally got her to talk to me about why, and she apparently doesn't feel appreciated in our relationship which left me awe struck because 90% of the things I do are for the betterment of us or our future.
We live together in our own home that I pay for.
She doesn't pay for any bills what so ever, I pay all of her personal bills (phone,school,car). Which puts a huge strain on me financially but I deal with it because I know we couldn't live together at this point if I didn't. She goes to school full time and doesn't really work because she has no time. Which I understand and I'm okay with the way we work for now. I work 50 - 60 hours a week but when I'm not working I spent almost every second with her.
I even gave her $200 to go shopping with this week 
After she complained about never having enough money for new clothes and such. I've literally given this girl everything I possible could(I know I said a lot about money but I give her more than that lol) I just don't understand how she feel unappreciated. And I don't know what she expects from me if this means nothing to her. She refuses to talk about ANY of our problems because she doesn't even try to see my point of view and just gets angry and walks away. I've never posted or asked for advice on her before but I could use some now.
<bot>: for the last 5 Years I've given my girlfriend everything I possibly could, she now says she's unappreciated and I don't know how to appreciate her any more than I already do.
