Dear Morning Show,

My younger sister happened upon some messages between my mother and a man who is not my father discussing things that made her uncomfortable. Such as how much the two of them like each other and where my mother should park at this mans house etc. As the oldest, my sister came to me with the information and I explained to her that this is a very adult situation and we don't have all of the facts. And as children we sometimes hold our parents to higher standards than we do others but at the end of the day they are just as human as anyone else. After a few days, I went to my parents home and told my mother that my sister had seen a conversation between her and this man while my dad was at the gym. She proceeded to lie to me and tell me that he is just someone she talks to and that they are just friends. I then told her that I knew she had been to his place and that details weren't important and she didn't have anything to explain to me but she may want to speak with my sister. Later she apologized and told me they had kissed but that was as far as it went and that the relationship was over. I am trying to be an adult about the whole situation but I can't seem to shake the feeling that I am betraying my dad by withholding the information I have. I love both of my parents dearly and I am completely torn. I had hoped as time passed, my issues would fade but as my mom calls me and wants to spend time together and go on a girls weekend or work an event together I find myself trying my hardest to get out of it. I can't stand the idea of being alone with her. I am angry that my sister and I have to suffer and feel this way because of her actions and indiscretion. Do I tell my dad, do I talk to my mom and tell her my feelings or do I just continue to suffer in silence? Please help!
