My friend told me she had breast cancer one day, in the previous few weeks to this, I had developed another friendship with another mum. My attention hadn't been taken away from my friend, I was just making other time to make new friends. After she told me she had breast cancer I started to get suspicious about it because she had been to the doctors, then to the hospital and had chemo tablets all within same week. Obviously I was devastated for her and said I would be there through it all, but after a few weeks we had a row and I confronted her about my suspicions because she didn't seem to be suffering with any side effects and she was drinking heavily which to my knowledge you can't do if you are undergoing chemotherapy, she then admitted to me that she had lied about the whole thing and the reason behind it was because she didn't want to lose the friendship. Since this has happened I have told her that I can no longer be her friend.... Aibu for completely cutting her out or do I forgive her?
