I remembered the first month when I started to detach. I felt numbness too. I just read. I kept reading. I was lucky that I had 3 weeks off that month. I read, & read, & read. I told myself I need to focus on myself, not him. everytime when I was worried about what he is doing or what would he going to do tonight after work. I went to pamper myself. I bought few nice things for myself, I went to have manicure, massage. CALLED & TALKED to couple of my friends (they know what I was going thru, so they won't found me annoying to call them anything of the day) I even went to have the xmas dinner at my friend's family, instead of with him & his family. It was very hard at the beginning, but time will help.
