Date with ex
Last year, my wife and I were separated for about 4 months. During those months I wAs away from the house, but we talked on the phone every week. At some point, she "ran into" an ex-boyfriend, and subsequently went to dinner with him a short time after.
One day while we were separated, I used her phone to get a number out of it and saw her ex's number. I asked her about it and she said they ran into each other and that was all that happened.
we are back together now almost a year later, and recently she let it slip out that she went out to dinner with the ex. Is it normal for me to be pissed , or just forget about it?
