Having to choose between friends?

I have been friends with a certain couple I will leave unnamed.  And well one of these friends was a friend to me first before the other came along.  And they had a rocky relationship.  And my male friend to whom I was friends with first took offense because I had let his girlfriend come back to my site after they had left previously. Being both of them and she approached me on messenger to ask if it would be ok for her to return and I approved and told her she left on her own so she could come back.  But with my male friend his resentment ran deeper.  He wanted me to acknowledge him as my first friend and for his help on my website.  And I had never disputed that and in turn he made the insinuation that I was like a sheep being a follower. And I in my final word to him that no one control me and I do have a mind of my own. In response to his word told him that I have the final word who gets booted off my site.  And my members also have that equal chance to have their voice heard.  But I had also reminded him of his own agreement with me that we both thought it best he not return to the site due to past drama.  As for the spat with his girlfriend well I took no sides and told them both this.And I especially reminded him of when he wished to remain neutral in a friendship I had ended with some one.  And I did accept that but he felt like I owed him in some way and I thought all of this was ended and that we were in good terms but I guess not and to think I was there when he needed someone to talk to and not judge. I even tried to be a comforting friend and sister to him but I guess that wasnt enough.  And he also felt I betrayed him when another of my friends and brethren had a falling out and because this friend was associated with the organization that he felt that had the right again to attack me and my organization my family.  He really wanted to be a part of this and I did tell him I will speak on his behalf and his past transgressions would be over looked if he gain trust back.  So now that I have been looking to contact him he slams me with a guilt trip and it basically felt like a slap in the face.  But I know I am the better person and simply told him I wish him the best and that I've no ill will towards him.  I just feel hurt and feel as if I lost two friends. As she does as he wishes and has no free will of her own. But simply reminded him in the very end that it was Satan's who gave us free will and if he wished to end our friendship that it be his choice. So that was that with him and his girlfriend. So tell me is that fair of him? am I wrong? or did I do the right thing.
