I guess this post is pretty cliche but hey what the hell. Ive been in a relationship for nearly six years. Ive always lived below my own means and am finally starting to change my lifestyle. That being said my girlfriend who ive always cared for has made me a softer man. Recently i tried breaking up with her for the second time and my heart always gives into her crying and sadness. Now im at a loss. She suffers from bipolar and depression and takes medication for them although she takes the meds i know she still fall into a deep depression. Not really sure what im supposed to do now because i do care for her but not in the way i used to. Any advice would be greatly appreciated

Edit: I do care for this woman and my own conscience as well. Basically ill feel like a piece of shit for throwing someone away for my own personal gain.
