Lost

I'm going through a breakup after 7 years. I'm hurting badly and don't know how to handle it. She was my everything my partner and my bestfriend. It's been rough over the years but I have always fought for us and given her whatever she felt she needed, but I guess it wasn't enough. She has become distant and some what emotionless. I don't know how to deal with this cause I have no support and ALL my feelings and emotions are kept within and it's killing me. We still live together and I just want to go to her for comfort or even just to talk because I'm dying here.
