Is He Ashamed To Be Seen With Me In Public?

So the guy i have been seeing for the past month invited me over to spend the weekend at his house. He than told me that he’s going to a party on Saturday night. So I ask him about about what am I supposed to do. His responds with “hang out here. I won’t be there for no longer than a hour or two. I don’t really want to go but I have to make an apperance” Is he ashamed to take me out with him? Or what could it be?
