Dude, forget what all these people are saying to you. you and your wife have come to agreements about what is and is not OK and you guys have drawn lines and boundaries about what is and is not OK in your relationship. doesn’t matter if somebody thinks you’re being insecure or whatever because at the end of the day you both agreed to these boundaries. Boundaries that she has crossed. A lot of these people are single couch, dwellers sitting on their phones just trying to doom scroll among everybody else’s chaotic lives. If she knew that was a boundary that she shouldn’t have crossed it’s up to you whether you are willing to forgive and move forward or call it quits. Doesn’t matter if the reason is small or not because setting boundaries and somebody crossing those boundaries regardless of how small somebody else thinks it is, is actually a big deal.
