Okay, that is so awkward because what happens when you run into him at the mailbox or in the hallway? Like, I would literally move out if I had to see a guy I hooked up with every single day at my own house. It’s one thing to have a crush on a neighbor, but actually sleeping with them is a recipe for maximum disaster.
One of you is definitely gonna catch feelings and the other one won’t, and then it’s gonna be a whole messy situation right on your own doorstep. What if he starts bringing other girls over and you have to hear it through the walls? Or what if you guys have a fight and he starts being super loud or annoying just to spite you?
You gotta cut it off right now before it gets any weirder. Just tell him it was a mistake and you guys need to go back to just being polite neighbors who ignore each other. Keep your curtains closed, wear headphones, and find someone to date who doesn’t live five feet away from you.
