My girlfriend of 3 years we and I got into an argument she broke up with me
Ok so I'm 27 and she is 22 we have been together for 3 years now and she has broken up with me 3 times before now. Each time she has backed away from me and asked for space. I give it to her and things go back to normal. This time we got into an argument about her missing her turn to come see me. (she lives an hour away now but we live together for 2 years while we where in collage) She said her hand hurt too bad to drive. A week before she slipped and put a hair-line fracture in one of the small bones in her hand, she has a cast on it now) I drove to see her instead. I told her that she needed to try to come see me next time, and to really try not just say she would. She got mad and broke up with me and this time she said it was because I was completely insinuative, and didn't care enough about her emotions. I didn't think a fractured hand was that big of a deal. Yeah I know it must hurt, but it's not like it's devastating. She also drives 50 min to school and 50 min home and has 2 part time jobs. I told her if she can do all of that with a fractured hand she should be able to come see me. Well she ended up going from telling me she loved me one minute to telling me she wasn't in love with me anymore, and she doesn't want to try with me anymore. So do you think she just got mad and said some things she didn't mean? Was I out of line? Is she just stressed? Is this really the end of our relationship? Obviously I do care about her I'm writing this at 4am because I can't sleep worrying about this. I love her with all of my heart and we have talked about getting engaged in the near future. The hardest thing about all of this is she said she needs some time to think about things for a week and she will call me when she is ready. So that is why I'm asking all of you what should I do?
~SINCERELY~ Heart broken.
