I found out my husband has been having an affair on me for 8 months with a 19 year old ( we are both 37 )....not only was he having the affair but he was living with her for 3 months ( he works all over the world and is gone for months at a time). After I found out about this affair I remembered something that happened 2 years ago and called that girl in Oregon...she admitted to having an affair with him also. Now when that happened 2 years ago, they of course both denied it and a friend of his was out there with him and he told me nothing was going on between the 2 of them. Since that time, my husband had set me and her up as "friends"...she would call me once in a while and would email me, etc. Now that I know they had been sleeping together , there are things about my husband and my relationship that I wouldn't have told her....I'm very upset about this and it is weighing heavily on my mind. Since she lied to me for years and pretended to be my friend, can I sue her for it....
