<human>: Give me a shortened version of the text

I don't have anywhere else to get this off my chest. If I pick up some advice, guidance on how to deal with my emotions, or just someone who went through something similar it would be beneficial for me I just need to let it out.

Yesterday was a weird day for me. One of those 100 to 0 in 1 second type of days. I came home to my wife in tears and that is never a good thing. I am welcomed by the dogs, but as I am my wife she tells me that I need to sit down and she needs to tell me something. My heart sinks, I fear the worst like "you're a shitty husband I'm tired of your shit and get out." I instead I hear the words that I never thought I would hear her say. "Back in July I kissed a co-worker." It was like the words were bullets and each one cause a hole in my chest. I go through the usual questions "how long (not long), anything else happen (no, no touching, no sex)." But the part that was the dagger was when I asked about naked pictures being sent to each other. She said yes. Again she said it didn't last more that a few days. But the naked picture part is the part where my heart just about sinks to my toes.  She feels horrible about the whole situation. She says that it was wrong, and I know she is, and can tell that she truly is sorry and that it truly is over and has been over for a long time.  

How can you move past your wife fantasizing about someone else and exchanging naked pictures with each other? I didn't ask but I am sure sexual comments where also said. She claims the pictures and everything is deleted and gone. But there's that trust level is sinking. Can I really believe everything she tells me going forward? I want us to work. I love this girl. We have been together for eight years and have been married for one.
