I cheated on my boyfriend with a mutual acquaintance [MF]

I [29F] cheating on my [29M] boyfriend with a mutual acquaintance [33M] that we see at parties and on our friends boat.

I went out without my boyfriend one night with our larger group of friends. I ran into a tall, built in a dad bod kind of way guy that was dressed like a standard hot southern preppy guy. We had shared friends in the group and have often run into him at parties before.

I was looking extra good in a tight black shirt and ripped jeans that showed off my genetically blessed ass. He immediately walks up to talk to me and asks “so… where’s your husband?” He knew my boyfriend was JUST my boyfriend. We have all hung out many times. He was testing the waters. “I am not married… and he’s not here. We’re in a fight….” I leaned into him and smirked. I needed to feel him wanting me. He ran his eyes all over me and finally after a few beers he said “you know I asked because… you’re extremely cute and you’re here alone” as he slid his hand onto my ass. I smiled and let it linger; it made me feel electric to physically feel another man want me. Especially after being so neglected by my boyfriend.
I stayed at the bar a little while longer before leaving. As i walked out in the opposite direction, he called out “when are we going to hang again?”
“At {our mutual friends} house!”
I didnt end up going to the party the next day. On Monday i woke up to messages on basically every form of social media asking to hang out for drinks. He was hooked :)
