Anyone like me?

I don't dislike people, I'm just very anti social. Lol. Whenever my husband invites our family/friends over, they're all downstairs watching football(or whatever) and I'm upstairs by myself. They know how I am and understand but my husband is getting annoyed with it. I just want to be alone and not cooped up in our basement with a pile of people. I just feel uncomfortable. I don't hate them one bit. Should I make more of an effort or just do my thing?
