You did the right thing by ending it. who gives a shit if its over the phone. The sooner you forget about that bitch the better.
Especially if she admitted to cheating AGAIN. There are like a zillion women out there with YOUR name tattooed to their ass. A short time down the road you're going to look back at this whole deal and kick your own ass for not canning her sooner. I was married to the bitch who cheated. It was the best thing that ever happened to me divorcing that woman even though a part of me still loved her. Its not fun or easy going through all of that but be glad you don't have a lot of strings attached. Quit tripping on being alone. Everything will fall into place man.
