broken, confused & lost...

I recently found out that my husband of 2 years was having Emotional Affairs. I have been with my husband for over ten years, and we are married for two. I always thought we were happy, I never thought we were perfect, but happy wasn't a question for me. I found out a year ago when paying the cell phone bill that he had been making phone calls and texts to this one long distance number A LOT! When I confronted him he told me she was just a friend, someone he met playing a game who had problems and they both discussed issues together, and made each other feel better by never putting a face to the voice and just listening. I believed it but asked that it stop. He told me he stopped it and I believed him, no questions asked. Here we are a year later, and I find out he is doing it again, but worse. I found a message he wrote to her saying how she was the only one who could make him smile and that "last night 'making love to her' was amazing.... and so on. Of course, with a broken heart I confront him to find that she is also from a game. He said it was a game to him, all a game of seeing how much these girls would want him. He admits its sick and says there is no connection and deleted all ties to it, in front of me (but who knows, technology these days you can reaccess anything). When I looked further into this game, and got into his account I found that the first girl wasn't just a friend, she wasn't part of woman #2 extremities (phone sex) but they would say I miss you, I love you, I can't wait to talk to you..... Seeing my husband write I love you to someone else alone was the most heartbreaking thing in the world for me.
