I broke up with my girl because she wont change!!!!I she's soooo stubborn :( She still loves me though?

She mutually broke up with me cause we always fight and argue over the little things. I gave her an ultimatum to change or else i was done.SHE thought i was bluffing :( We have been tigether for 8.5 months and her excuse is "its unhealthy and we argue all the time, you get pissed at me over the little things and my diet and excersise habits". This all is true but it has definetly gotten better over the last 2 months. Im not perfect and i realized some of my complaints against her were superficial. She says she still love me and i know its true. She is soooo stubborn though, and she says she doesn't know if she can change :/ I have helped her move 6 times, paint her garage, dealed with her smoking habits, her attitude,stubborness, poor diet,excersise,in fact the whole reason she had tomove was b cuz she mouthed off to her teacher and she had 2 months left of nursing school!!!!!! her teacher dropped her, she had to move out cuz she couldnt pay rent, (6 times), she says we have lifestlye differences(i like the beach, she likes the countryside cuz she has a horse). I dont mind going out to c her horse and all, its just that she told me she would change and that she would go to the beach and workout but not once!, has she done any of these things. However, she has something that ive never felt from a girl....EVER. She still wants to hang out and be freinds, but she doesnt want a relationship. She said no for a future one cuz she said she doesnt know what the future holds. Ladies, be honest with me please.+ she has been in scholl for 6 years and has nothing to show for it.She has 1 year left cause she ****** up and ive had to deal with everything(moving,smoking,bad habits, attitude, stubborness,blah blah blah) all she has ever had against me is my anger.......CAN YOU BLAME ME?! I still love her though.... LADIES, do u think there is a slight possibilty she would realize that she was wrong, change, and want a relationship in the future???
