Together since 18, 30 now with no kids. She started a job at another place with better pay four months ago. One month ago tells me she has been miserable for the last few years, does not want a divorce but wants space. Two weeks ago gets her own place. I did some digging on this guy she would text who she works with. His Instagram is filled with pics of him at the gym and my wife likes all of them which even makes me feel more like shit.

Anyway I have drove to his house a few times at night and her car was parked there both times. In my gut I know what she's probably doing but I have not confronted her. She denied there was someone else to the core and was angry at me for even suggesting that.

How can I just handle this with my dignity?
