Hi everyone, first time here. I've been with my partner for over 20 years, no kids and we haven't had sex for a few years. I've always been faithful and he hasn't. In February I was looking through his phone and saw all these messages from his first love (they were engaged and it was serious). She sent photos from when he took photos of her back then semi naked (and she was stunning) and they had been calling each other every day and him saying I can't speak I'm with a friend (me!). I messaged her and i wasn't polite, as I was so shocked. Then she blocked me. I confronted him but he said she's an ex. This was nearly 9 months ago and I can't move on. They'd been texting since January. Am I driving myself mad and it's nothing? What drove me mad was the fact she blocked me. Surely if she had something to hide she would tell me? I just keep going over it in my mind.
Thank you in advance ☺
