Husband and I both 35. He got very drunk on his front porch and I came outside and found a woman on top of him. How do I move past this in our marriage?

Yes, I can’t believe I’m even writing this. <br><br>We have a nice little house in a nice little neighborhood. I was doing some yoga in the upstairs bedroom (which has a perfect view of the front yard) and noticed 2 people sitting on a blanket on our front porch. I could see both people had beer bottles and I could tell one of them was my husband. The other person had long hair so I just assumed it was a friend stopping by and I thought nothing more of it. I went back to my Yoga. <br><br>I looked about 5 minutes later and they were still down there. And then I could see he was sitting on the blanket and she was straddling him. I could tell she was a lot bigger than her because I could see her entire frame from our upstairs window. <br><br>I put on my shirt, ran down stairs and out the door and I could see that she was straddling him. She jumps up when she sees me and he falls over on his side. I couldn’t believe what I was seeing. I just kept saying, “who is this?!”. She said, “I’m sorry I didn’t mean to hurt you”. <br><br>His is a bit drunk so he makes up some story about how he was walking the dog, and she stopped him and said she hadn’t had a kiss in a year so he offered to kiss her and it went on from there. He said it didn’t go all the way but I could see her adjusting her pants so…. I told her to get off of my property and to never speak to my husband ever again. <br><br>Now he’s saying, “It didn’t go all the way”. He’s saying he regrets it and hopes I can forgive him. I don’t know how to deal with this right now. He is drunk so I don’t know if I should address it tonight or wait til the morning. The only reason he was on the front porch was because he was drinking so much I told him to sit outside so he wouldn’t make a mess in the house. I gaged him a little too much tonight and this is where we are. I’m just lost…. And very hurt.
