After 10 years with DP I feel I need to leave. We have no kids together. He never supports me emotionally through anything and after a recent cancer scare I feel I can't do this anymore. I have told him how I feel and what I need but he doesn't even reply. He just thinks I am having a go at him. I can scream and cry in front of him and he just walks away. I feel bad about leaving as he isn't a bad guy, but I need more.
