Date or not

I have been dating a guy since January we have not talked about being exclusive but when we have plans on weekends without each other we do tend to ask the other if it’s not a date and who are we with. Yesterday Friday he said he had plans with his cousins dso I made my own plans he did not post anything on social media and usually he does especially when it’s with his boys. Should I ask him why he didn’t post anything, should I even be concerned or should I just ignore the whole thing and continue talking to him normally?
