Update:
Things seem to be moving slow. She sleeps in the bed with me, she kisses me goodbye, but she still acts distant. I try to help her everyday with her real estate job and say encouraging things to her. I don't bring up future talk or R talk, and when she does I agree with her and tell her I was horrible. She will call me to see how I am doing. I lovingly detach myself from her when she gets upset with me. She is constantly asking what I am up to and I just tell her I'm at a friends or I am with a friend doing blah blah. I know things won't change overnight, and it will be a slow process, but when she gets upset with sometimes I feel like giving up. My heart can't take such a beating. My sisters relationship is not going smoothly and I feel like my life is falling apart. I have to remain strong and be the rock.
