I found out my partner of 7 years cheated on me 3 years ago. I did the worst thing and went through his old phone and found messages with a girl he used to work with that suggested he wanted to leave me for her. I remember we did go through a rough patch at the time, but we managed to work through it and stayed together. I was never suspicious there may have been someone else involved even though he used to talk about this girl all the time. I just accepted they were good work friends.
We’ve since gone on to buy a house together and even got engaged. I’m torn whether to confront him because it was so long ago and I found out by completely invading his privacy. But he thinks he got away with it so what if his head gets turned again and does the same when we’re married?
I think I could forget about it and move on but I want him to know he didn’t get away with it. Any advice would be very much appreciated.
