Friends w Benefits

So me and this guy have been sleeping together for the past 6 months we’ve kept it casual but there has been times when we would cuddle and have conversations about personal lives or he’d invite me to dinner. We even talked about moving together. I think he cares.. sometimes he gets jealous.. but idk.. The sex is amazing!!! Blows my mind every time !

today he asked me to come with him to pick up his little brother from the mall.. so I went with him. I opened the door for me to sit and there was this Victoria secret thong and condom wrappers. I wasn’t mad.. I was sad. It made me kind of shut down the whole ride I was just silent (like we aren’t together... I get it. I’m just idk 😞) what should I do?
