Update #2: Is my wife cheating on me
previous post: Update: Is my Wife Cheating on Me : r/Infidelity
About a month ago I went to a group hang out that my wife was having with her friend group. I told her that I would not be able to make it because of work, but I actually went and planned to be there to crash it at around 8:30pm. I never posted an update though because when I arrived there wasn't much going on. My wife and her friends were playing monopoly and other board games with her friends around a table together. They were surprised I was there but they all greeted me and I joined them.
On July 4th we went to a cook-out picnic to watch fireworks and stuff with her friend group and others. This gathering was much larger, with probably about 70 to 90 people. The guy (I'll just call him John so it is not confusing whenever I say "the guy"). I saw John was there too. Even before when I first met him while dating my wife all those years ago, I never really liked his vibe, plus with what has recently been happening, I just chose to not really acknowledge him. Everything was quite normal for most of the night. I endured some social interactions with John here and there and everything was quite normal for the most part.
The weird part began when the fireworks started. Basically my wife and her girlfriends were dancing in the grass field and cheering and just kind of goofing off with music from an amplifier playing loudly. Some of us were buzzed others were drunk, and then I saw John suddenly appear as my wife was cheering and dancing next to her friends with her arms up and John holds her arms from behind her. One of John's friends (at least I am assuming his friend) does the same with a girl who was dancing/cheering next to my wife, and I thought to myself are these people crazy? because I know that girl is married too, to an acquaintance of mine (one of the only guys I would call "friend" in my wife's group). I froze up sitting in my chair by the food and waited to see if he would let go and then I can confront my wife about it. But he never did and I got antsy, so I got up and started speed walking toward them. I naturally don't have a loud voice but I yelled out "hey" as loud as I could but even I had a hard time hearing myself with the fireworks and the music playing. When I got closer to them, I can hear my wife saying "duuude" at John. I put my hand on John's shoulder and I grabbed my wife's hand and after a few seconds John lets go and dances backwards into the group. Me and my wife sat together by the food where I was previously sitting and I asked her why he keeps touching her. She responds by basically saying she's sorry and that she wasn't aware who was touching her at first and that John is just a moron. At this point I was a bit glassy eyed and probably filled with a decent amount of adrenaline. A random guy who was sitting close by heard and kind of chimed in saying how some random guy was grinding with his wife and they are "acting a fool" but that this kind of thing can just happen on dance floors and at the end of the day his girl always comes home with him. The rest of the night went without any problems.
When we got home, we talked a long while about everything. But the conclusion we came to is she agreed on my request not to go to hang outs with her friend group if John is there. I will still attend at random times as I have been doing but so far this is the resolution that I am content with after our long conversation. My mind is a little scattered right now so sorry if I didn't explain very well, but I even have half a mind to text the husband of the other girl I saw being held to let him know but I am also aware that this all could just sound so weird for him and there could be an off chance that I just start making straight up direct enemies with some people from my wife's group if I start sticking my neck out.
