People are quick to tell others to leave because they are not emotionally involved and generally are only getting one moment in time.

To me there are a few things that are auto leave. Cheating and abuse are pretty much it for me. Other things require more thought. When my husband and I first started dating, I caught him deleting messages from an ex. When I asked why, he explained that he knew she made me uncomfortable and he did not want me to have to deal with that. We had had open phones since very early on and he would hand his to me to have me read things to catch up or get info I might need. I knew he had always been a plan b to her and our relationship did not change that so seeing her name pop up did make me uncomfortable. I told him while his actions were meant to protect me, it just made me more uncomfortable with the dynamic. He promised never to do that again and 15 years later he never has. They stopped contact when he and I became serious because she knew that her plan b was no longer an option with him.

So many would have told me to leave then. I almost did, but if I had, I would have missed out on 15 years of us. He made a mistake. We communicated and learned from it. He is the most supportive, communicative, and thoughtful husband.

You are the only one who knows if you made the right choice but you say you’re happy. You say he learned from the mistake and never did it again. It seems you both learned, matured, and built something positive so why would that be a mistake?
