I'm lost, can't believe at 68 I would be in this mess. Fourteen weeks ago this whole thing started. We have been married 45years and very much in love. We have two beautiful children and two beautiful grandchildren. In August my wife who is 66 suggested we go to a neighbors going away party for their son who is 24 and going into the navy. We went and had a fun time. What I found odd was the way my wife wanted to have shots with their son. We left and nothing was ever said about it. One week later we were in bed at night and I heard my wife texting on her iPhone, she had her back to me, I could just read the top message which said "don't you care about us anymore". When I tried to read more my wife felt me move and erased the text. The net day she said she was just texting our son which was not true. I began to watch more closely. I have never distrusted my wife. Our sex life has always been great even at our age. We are both retired and are always together except for when she has her nails done every three weeks, which takes about 2 hours. Her nail girls shop is 5 minutes away. Never really paid much attention. I did notice her sexual desires changed during this period. For her next nail appointment she had a hard time getting the time slot she wanted. It was so late in the afternoon not her normal time. When I asked her why, she said she just wanted a change. The time was set for 4 o'clock our neighbors son gets home at 4:30. The day of her appointment she wore her fanciest underwear which is not the norm. Sure enough 20 minutes after she left he left his house. When I confronted her about this the next day she became very angry, she told me I needed to see a doctor, I broke down terribly. I think she has had two more visits with this young man. After the last visit I heard her mumbling "it's over it's over" . Two weeks later the boy left for the service. When ever I talk about this she angrily denies everything. One day she was crying and said I wish you could get me a lie detector test, I said are you serious , she said yes, I said ok. Then she said you would do that to me, I said you asked for it didn't you? She agreed. She took the test and failed it. She still will not admit anything. We have since seen a psychologist 4 times. It's such a mess now. Our children have stopped our baby sitting and are both sick to death over this. I myself can't sleep or eat. I went from 214lbs to 183lbs in 14 weeks. I just can't get the thoughts and pictures out of my head. Any help would be greatly appreciated.
