Office Party With My Boss!

I'm a 28-year-old guy, and I've been happily married to the love of my life for two years. But something happened on an office trip with around 100 colleagues that's bothering me. We had a big celebration and lots of fun at a party. I ended up drinking a lot and was quite drunk. Around 2am, someone rang my hotel room's bell. When I opened the door, it was my boss. My boss is a 35-year-old woman, and she's also married. I was surprised and didn't understand why she was there. Instead of explaining, she came closer and got into my room to sleep. I was confused and didn't know how to react, especially because I was drunk. We had joked around a bit during the party, but I never expected something like this to happen. The next day at work, I felt really awkward around her and couldn't look her in the eye. Now I'm not sure what to do. I don't know how to handle this situation, and I'm worried about how to talk to my wife about it. I'm also concerned that this might happen again during future office trips. I'm feeling really lost and don't know the right steps to take.
