Met my ex in rehab

He was my best friend and my support in all aspects of my life. We lived together for almost 2 years. I lost my job a month ago and got a new job that starts Feb 3. He told me he could take care of things so I could get back on my feet but he completely abandoned me. He works 2 jobs and worked longer hours and left me home alone to deal with myself. There was no support and I called him last night and he told me, everything was my fault. I was going through an emotional time switching jobs and he kicked me out before I could start. The job I took was closer to my house and now I can’t do it because I am too far away. I am financially struggling, my things are still at his place and I am so scared to get them. I just want my best friend back.
