Husband cheated, any thoughts?

I found out my long distance husband cheated on me with some girl he worked with. He’s now at a different job and while I suspected he was up to something, I looked into his phone. I found a bunch of messages with his friends saying how he and this girl officially broke up. I confronted him about it. We broke up but still talk and I still visit but not as often. Every few weeks. Today we kinda officially officially became “friends”. I know how stupid that sounds but whenever we talk it’s either I seem ok or I’m an upset mess. He finally accepted and stopped trying to get back with me. I ask him how long he was with her and he will not tell me. I feel like I deserve to know given what’s he’s done. But he will not. In my mind I don’t know how to cope. The only thing I’m trying is distracting myself and going out places with my friend. I’m a wreck and it bugs me so much that he won’t tell me how long he cheated for. All advice or suggestions or opinions are welcome. Please tell me what you think.
