What's the difference?

I'm not sure what I thinking or what I want to know. I think I hope Mercy reads this and emails me some thoughts. I know that I have blogged about this before but still wondering. What is the difference between friendship and co-dependency?

I have many friendships that have gone by the wayside. I would like to know for sure if that is what is happening with Karin and Mercy. I had never been as close to a woman as I was to Mercy, was closer than with my ex. Now, I know that my relationship with Vicki is even closer than what Mercy and me had and not sure how to talk with Karin and Mercy now. (I guess I should say I hope Karin reads this too.) 

To a large degree I understand that my sexual addiction has become a problem with us. Maybe more in my head than in reality but I pretty sure that it is there too. There is no way to totally repair the damage done but it can heal. 

Anyway, I really want the both of you to know that I really miss the friendship we had and that I still care very much for you. I will be the best friend I can and hopeful that is good enough.
