Probably nothing, just a little bravado.
Thing is many men might say stuff like this but you are only picking up on it because you are a CD. I wouldn't over think it, you said you like him so he must have some good qualities, you may find if he knew about you he wouldn't stop apologising.
I have a friend that acts all 'blokey' and bravado as that is how he was brought up, he comes from a tough community, friends from school in prison etc. Yet I know he is actually really caring and sensitive. Most people act how they think they 'should' act.
