After nearly two years I think it's finally time to move on. My girlfriend and I live together which is what makes this move so tricky. I'm not sure how I should approach a breakup. I am not the man I should be and must work on myself to become what women need but I feel it's impossible while in a relationship.

I have no idea how I can end it, what to say and what to do? This will obviously be a painful experience for her and nothing I can do/say will lighten that load. Living together makes things far more complex as her life is in my apartment which means she will resist even harder to try and stay. At the end of the day I know she isn't satisfied with the state of our lives and will slowly start to be come less attracted to me even more over time.

How have you guys handled situations like this and what should be my strategy? I also think she may have been unfaithful but have no proof (unlikely, but trp makes me paranoid...).
