Cheating OCD?

My wife and I went to her companies holiday party after New Year’s Eve. One of her coworkers has sometimes been really friendly/flirty with me and prior to us ever really conversing, my wife told me she didn’t want me talking to her because she was the type of girl that got around. I never thought I did anything wrong by being polite and talking to her if she spoke to me, although I have thought her coworker was attractive even though I’ve always told my wife I didn’t find her attractive when she’d ask me (because why stir up trouble when I knew I’d never do anything) thoughts are just thoughts. Finding someone attractive isn’t cheating. So fast forward to the holiday party, my wife tells me to make sure I stay away from this said coworker. I know my wife feels away because this coworker is bisexual and is pretty and my wife has told me countless times that her coworker is beautiful (so maybe she thinks I’d find her attractive too) so I try staying away from her coworker that night but of course alcohol was going around and it made me feel good to have people compliment me all night (given me and my wife haven’t had sex in what feels like months, which we also have been having issues with) and of course said coworker said I looked nice.. it made me feel good. I felt guilty about feeling wanted. Her coworker looked nice and walked by me and her coworker noticed me looking at her and said “what?” and I winked and said “nothing”. which wasn’t okay what so ever and realized that within seconds after it happened. Her coworker just proceeded to walk. Later one we all have shots and her coworker suggested we all kiss.. (my wife, me and her) I said absolutely not. I told her if my wife and her kissed I’d be okay with it but I would not join. It started a whole thing and we ended up walking away. Her coworker later came around again after we took shots and told my wife that I was tempting her with my smile. I couldn’t believe this was happening. Her coworker was heavily intoxicated as well.. so I know that also had a lot to do with it.. After that I notice her coworker leave out the front door and I was worried she’d drink and drive so I did go outside looking for her (which wasn’t a good idea either.. given my wife had issues with me being around her) I never found her but I also realized once I was outside like “wtf am I doing? This isn’t okay and this isn’t right” I went back inside, my wife didn’t notice I was gone but I feel guilty. I know I cannot tell my wife because my wife has anger issues sometimes and I know this will not end well. She confronted her coworker the next day and her coworker said she had no recollection of what had happened and apologized for her behavior. I guess I’m posting this in efforts to feel better or get advice? My OCD sometimes gets the best of me. I feel guilty for somewhat feeling good that I felt wanted by someone because me and my wife haven’t been intimate in months. It scared me that I felt like I could’ve acted on impulse based on being wanted by someone. I know deep down inside I’d never do anything but it still doesn’t feel good that this all happened.
