Should I fight for her back?

I hope to get some good information. I have been with my girlfriend for 5 years, all this time she as been away at university. I have recently finished with her because of the way she treated me, we have broken up 3 times in the last year each time lasting 2/3 weeks. We argue a lot for example when she is home at weekends she would rather be with her friends and I feel I have spend the last five years waiting for her. When she is back she stayed at my house, more recently I was going to buy a new house and put it in both our names. My girlfriend and her mum wanted to collect all her stuff such as bits of furniture at keep it at her mums until I moved. As my girlfriend was going to move in with me properly I questioned why they called it her stuff and not our stuff. She has done other stuff like booking a holiday me not included. I struggle to find her commitment and find my self dumping her all the time trying to get a reaction. I help my family a lot and she hated me doing thing, she always puts her friends first. I love her and feel I have wasted 5 good young years of my life. She is a vet and I never have much money I think she feels she can do better then me. Should I try and fight for her, she said we are two different people as I have tried to get her back. Maybe I should just let go.
