Df's best friend (Mark) and I have been having an affair for a few weeks, and when Df (Johnny) found out, he recorded the evidence (tape recorder) so he could have proof. I think he may have found out I was faking my pregnancy, too, because when he caught Mark and me kissing, he went upstairs to our bedroom and shot himself. Now Mark wants nothing to do with me! He says it's my fault that Johnny killed himself. With that, and my mother having breast cancer, I just don't know what to do. I feel lost.
