That is your disease talking. Don't let it win. Two months may not be enough time for you to grieve the loss of the relationship. I know that when I was younger and broke up with a long time boyfriend it took me close to a year before I was able to not think about him all the time. It is no different because he is an addict. It is still the loss of a relationship. Give yourself the gift of more time. Prayers that your obsession eases. Hugs, Marle
