It can be an agonizing decision to let them go. However, for me, I am finding that the difficulty in letting go was so much more about ME, than the fact of missing him. I have had "some slap me in the face" revelations about what motivated my actions, what made me feel certain behaviors were acceptable, etc. I sure have some work to do on myself before I can be in a relationship with anyone, let alone a person with an addiction. Keep up with your own meetings, lots of self love, good literature (if you like to read), coming to these boards, and believe me as time passes you will notice that you have more brighter days, than gray.
