Hi Helen, I am so angry but feel so betrayed too. I found my husband in bed with my sister and I don’t think it is the first time he has cheated. Me and my sister are quite close and we talk lots but I have found her quite distant lately and now I know why. I am so upset but also so angry and feel like they have both disrespected and betrayed me just to get their own kicks as I doubt they are truly considering a relationship. What should I do?
