Omg what happen

So for some reason I was suppose to meet up with one of my old boo thangs to have sex or whatever something quick fun. So I got to the house and the vibe was awkward between us but we tried to talk about things and stuff. As he was getting ready to start the mood. I kept doubting the situation and I realize how much I miss my ex lmao so I tried to avoid things and kiss my boo and go with the flow but for some reason I wasn’t feeling it at all. So right when he was about to insert his penis inside me for some reason I wasn’t feeling it so I had to tell him no 👎 I don’t want to do this anymore. So he got mad about it cause he said wow you really about to do this to me now ? I said yes I have to go. I feel so bad but was I wrong or can anyone tell me wtf was that all about. 🤷🏻‍♀️🤷🏻‍♀️🤷🏻‍♀️😩
