I'm not sure if this is the best place for it - I'm still new. I recently lost my friendship with my best friend, Zack. He had been having a lot of trouble with his wife, and I thought I was just being supportive, but he told me we we having an emotional affair and he couldn't talk to me anymore. I'm depressed over the loss of a friend, guilty even though I thought I was just being supportive and a friend. I just feel horrible. And part of me wonders if he was just using me until his marriage got better. I just needed to talk about it, and I don't have anywhere else.
