I 56M have had a feeling they my wife 50f has been cheating on me for a while now.

We have a dead bedroom and she claims to be low libido. Yet she do it herself regularly. Much more regularly than we have any physical contact.

There have been multiple deceptions and lies that have been red flags as well. I do not think this is a regularly occurring thing. I believe if it is happening only occasionally and only when there is an opportunity.

A little over a month ago I decided to track her movements with a GPS device. I work away and sometimes she comes with me and sometimes she does not. For almost a month she was always where she said she would be. Even when I was away.

One day recently she was driving down to stay with me at work and she diverted once she got to the place I work in. She drove straight to a place there was full of hotels on the other side of town. Her car was in the parking lot for exactly 1/2 hour then she stopped at a couple of stores and arrived at our house there.

The next day she left the house while I was at work and drove straight to the same area and again her car was in the parking lot for 1/2 hour then she went shopping at a clothing store and then grocery shopping before returning home. That evening she only told me about going to the grocery store. I took the opportunity to tell her her skin seemed glowing and asked her if she did some facials.

But why lie about it? Any thoughts? By the way the car is in my name so there is no legal problem with placing a tracker in it.
