Never going to tell my husband

So I was deleting some old pictures from my phone. And I was wayyyy in the rabbit hole like 2015 in the rabbit hole when I came up on me and my last ex. It was a whole ass album and it was filled with the memories our daughters ultrasound pictures (ended in miscarriage) we looked so happy in the pictures. I didn't text him. I wanted to but I didn't. We only broke up when I miscarried our daughter. Just looking at each other made us cry. He was my first. Idk I guess it's just depressing. I am happy with my husband and we have a beautiful son together and a house. Idk maybe I should just delete and forget.
