Hmm...and then there were three?

Each day sheds light on who a person is through their actions current or past. Even though yesterdays festivities were tons of fun I did have a few "down" moments. Its amazing how easy it is for some people to go behind their friends or spouses backs, completely disregarding the feelings of the other party involved. I'm still not quite sure how to or if i should confront the situation. At this point the only thing I am sure of is I feel betrayed and sick to my stomach. There are so many question that I want answered, mainly "why?"
