Boo, I'm glad you have us tonight. I think readerbaby is right. You need to separate yourself from him tonight. Give yourself some space right now. Do you have family or a trusted friend that you have shared this with yet? I know you don't have phone access...but maybe through an email right now? Someone who knows you well, someone you can trust?
I am hurting for you right now. I was caught completely off guard by my xah's affair. Our marriage ended in the precise moment that I found the evidence. He sobbed and begged forgiveness too. For about a day. I got about 2 seconds of satisfaction from it, but it didn't matter. That kind of betrayal cuts deeply, and I am truly sorry you are having to experience this.
We're here for you. I'm sending a lot of prayers up for you. We'll continue to be here for you.
