I've been with my gf for 5 years, we have a very good relationship and have supported each other through tough times - when her parents got divorced and when I had a series of family problems. I care about her and I am pretty sure she cares for me. I am 26 and she is 24.
But lately I have been fixated on where our relationship is headed. We are living together and so far it has been... okay. I say okay because so many of her habits and some of her actions drive me up the wall and I have to stifle my feelings otherwise I would be yelling at her everyday. One of my biggest concerns is her lack of common sense, she is book smart but she does stupid things like washing her shoes in the kitchen sink (right next to the clean dishes) - no concern about splashing mud.... She throws away all of our used bottles, even after I wash some of them and set them aside for re-use. She has a slight neurotic personality such that she turns small problems in to massive ones - she lets problems drag out for long periods of time and complains about it all to me to the point where I am fixing her problems. She is really dependent on me, she couldnt even complete a FAFSA or even a tax return without my help. She cannot even cook to support herself.
I am in medical school and sometimes she doesnt really understand the pressure I go through just to pass my classes. I try to talk to her about these issues but she is really sensitive and acts really hurt.
I feel like these traits are not ideal in a wife and are strongly detrimental in a mother. The way things are now I am able to be happy with her for a good portion of the day (when I'm not putting up with her ridiculous demands), but I dont see a future in this relationship.
Should I try to make her change or just leave?
