Pain

I have been feeling a significant amount of pain in the last few days so it's something that I have been thinking alot about. Why am I feeling it and where is it coming from? Is it the actual experience of withdrawal from an addiction or the fact that I am hurting because of the loss of someone that I cared about and talked to every day for 5 months? In actuality, it's probably a combination of the two.
While I realize the decision to end contact with him was my own, the fact that he hasn't tried to reach out in the past almost 4 weeks is extremely hurtful to me. I am neither surprised nor expecting contact however if there was one iota of caring ever present, he would have tried to make contact in some way. I think this seems to be his final "fuck you". Ironically I thought that he had lobbed all he had in his arsenal at me by now.
