FWB ADVICE!!

So I met this guy at the club in January. me and this guy been FWB for about 3 months now. This is my first time having one. I know how they typically go. Just hang out casual sex which is what I want no relationship.this weekend it was a typical meet up but he told his friends that I was his girl and when I was leaving he hugged me for a long time and then said he was gonna text me and I made it clear I didn’t want a relationship when we were texting later that day and he was cool with it. I posted a pic on my snap that was 🔥🔥😎 and I try talking to him just to see if we were still gonna hook up (I have son so we plan ahead for babysitter) and he just leaves me on R? I don’t know if I made him mad or upset because I told him I didn’t want a relationship. I just don’t want to lose my friend.
