I dont know what to do..

My so has been acting very strange since we got into a pretty big fight last week. The fight was my fault and I've tried to apologize a hundred times but he seems distant and not as affectionate. He says we are fine but I don't feel like we are. I don't wanna pester him about what's bothering him but I don't know what to do....we've been together a little over two months but I've known him over a year. Any advice ladies?
