Losing the battle

My wife has a male friend, who is married but marriage is having problems. I dont trust this guy cause I can see the way he looks at my wife and i have expressed this to her. She has basically told me she is an adult and can choose her own friends and I just have to trust her and accept it. We were supposed to go see other friend that we both have but she is all of a sudden afraid of the weather but if we went to his place that was ok. i feel that Im loosing her if I havnt already and the harder I try to explain the more distant she becomes... Out of ideas

Chaser, Unfortunatly what your wife is most likely doing is concidered an emotional affair. I just found out a week ago that my husband of 15 years was having an emotional affair. Google it and it will tell you every detail. It will tell you its not ok. When the friendship affects your marriage its gone to far. It helped me read the facts because it reassured me that what I was feeling was right, was normal. She does need to end the friendship/affair if she wants to make it work with you. She will insist they are just friends nothing more. She will deny its an affair but it is. Your wife is giving her heart to another man, sharing her thoughts that should be for you. I am not saying this to hurt you I am saying this because I am in it right now. I share your concerns. Print off the description of emotion affair, let her see that its not right. I pray for you. For me this was the hardest thing to deal with in myh whole like. Im sorry
