So me and my ex lived together for 16 months. She didn't treat me well, she didn't trust me. I didn't do anything to deserve it. She was just extremely insecure. I ended it for good a week ago. Now every morning when I wake up, she's the first thing on my mind. I miss her, I want to call her. Sometimes I'm almost in tears. Does anyone have any advice on this or how to deal with it? Or has anyone else experienced this?
