Should I be mad

My boyfriend has a busy work schedule. We haven't seen one another since Saturday. He always tell me how busy and tired he is but today when he got off of work, he went straight to chill with his friends instead of seeing if I wanted to see him. Mind you he see his friends everyday they live in the same area. I really don't wanna make a big deal out of it but I really feel some kind of way. He just posted a picture on Instagram asking if anyone else wants to hang out.
