I wasn’t expecting this

so you know this wasn’t intentional 🤦‍♀️. so now I guess I learned that new cars can be useful on catching cheating husbands 😡. so this morning I went to drop off my kids at school in my husband’s car and when I arrived home, his car automatically synced in to his phone Bluetooth. I was curious 🤦‍♀️ so I decided to look at his contacts (Let me be clear his car got connected to his phone Bluetooth automatically and this wasn’t intentional) and I noticed one of his contacts was “Amor” I clicked on it figuring it’s probably me because we sometimes call each other “Amor” but nope! It had a way completely different phone # on it 😡. He apparently has my # under my nickname that which is a nickname that all most people call me. I asked him and he just stood quiet and then he said is a girl and that’s it 😡. Now I don’t know what to do. I also want to add that I clicked on the recent calls he made and it looks like he just called her this past weekend. I so I wasn’t expecting this and I don’t know if I’m overreacting. What you think?
