O.K. So I'm gonna try and keep this short and sweet.... Friday night my mother and father were off to (one of many) high society gala things... and just after they had left, I went to the table that we have in the front hall of our house to get a ciggerette out of my pack and just then my mother's phone lights up with a TXT message (the phone was right beside my smokes) the message read..."So your at a lovely dinner party, and im recovering from great sex thanks for a fabulous time he he he" Well needless to say my heart dropped to my feet. A little background info.... My parents have been together since they were 13, have been married 39 years and we own a family business where we all work together. My mother pretty much comes and goes as she pleases (always has) and does not work Fridays..... Moving on I became inraged and it was only growing more and more.... I started to go thru her contact list to match up the number the TXT came from with a numbers in her contacts and BAMB.... there it was! The number was from a woman!!! W T F ? There was also a voice message on her phone from this woman from earlier that day saying that she was at such and such an intersection and that she would probably be there befor 1:00... I am a total wreck over this and have not been able to sleep all weekend. I have't talked to anyone about this, not even my BF. He knows something is bothering me but this is a family matter and a potentially emberassing one at that. My hands are shaking uncontroably as i am typing this... I have not really spoken to my mother all weekend and when i have i have been cold and short with her. I think she knows that I came accorss the TXT on her phone. After work today I was going to ask her to explane herself the TXT to me. And try NOT to jump to conclusions. A) Is it safe to assume that she is cheating on my father? B) What should my approach be? PLEASE PLEASE HELP me with any advise you can give.
