My brother dated this girl for three years until January 2007. It was a long distance relationship for about half that time, but it was very serious almost to the point of marriage. She dumped him because she was cheating on him, and I knew that for quite some time until he finally came to his senses and realised it. They never spoke for several months, but started to sometime in the summer--- daily. My mom found out about this, and she became very upset. Nobody in my family likes her anymore. My mom had an intervention with him sometime in August, and he told her a few days later that they decided that it was best they never spoke again forever. However, I was on the at&t online account, and I see her number on there everyday. Nobody but me and him know about this, and my mom would lose it and become very depressed if she found out about this. I believe that it is in my brother's nature to forgive rather easily, and I highly doubt that they've started something again. Besides, he's a big boy (26). My parents, on the other hand, have Irish Alzheimer's. What should I do? Let it go? Talk to him? Tattle? Thanks.
