I(M)(56) and my wife(F)(53) have been happily married for 30 years. 2 days ago it was our 30th anniversary and I had planned a romantic night, I was going to take her out to dinner and we would go on a romantic walk to where we first met (in a local park). However, when the day came she said she was meeting up with one of my friends, Tom(M)(55), I asked her if she remembered what day it was and she said she did but didn't think it would be a big deal. I was upset and felt defeated, and decided not to interfere. For some background information, I was with Tom the night i met my wife. We both fell in love at first sight, however she chose me. It's been 33 years now and I think she regrets her descison. Now fast forward to around 8:00pm that night, my wife is out with Tom and I'm sitting home alone drinking whiskey at our kitchen table, when suddenly there's a knock on the door. I opened the door and my wife's friend Rick(M)(54) was standing there. He asked if my wife was home and I explained the situation to him. He apologised and said that it was a shit thing to do. He sat down and poured himself a glass of whiskey. We sat there and drank together, talking for hours, and I have to say it was the happiest I had been in ages. It was around 11:30pm I think (that's a guess I was pretty drunk) when i got a text message from my wife saying she would be staying the night at Toms. I cried. I thought she loved me, but I knew it wasn't me she wanted, it was Tom. At this point me and Rick were on the couch. He hugged me, wrapping his arms around me. It felt so wrong but also so right. Suddenly, without even thinking about it, I kissed him. Rick just looked at me. We both stood up, Rick said goodbye and left without another word. Now, I'd like to say I'm not gay. This is only the second time I've kissed a man. I was just drunk and missed my wife. I feel guilty, even though I know my wife isn't innocent, I still know what I did was wrong, so AITA?
