My one wild night out of nowhere.

Hey, I’m 23 in a generally happy relationship. Last week was my friend’s birthday party, I had some drinks and got flirty with this random guy. We ended up going back to his place together. It felt spontaneous, exciting, and just... thrilling! He said he liked me too. So yeah, what do you think? Is it wrong of me to feel this way when everything else is great at home?
