Lupin's relationship with Harry

I've recently reread PoA and there's something that's been bothering 
me. Is Harry hurt that Lupin doesn't attempt to reach out to him like 
Sirius has? They were both one of his dad's best friends, so does he 
ever wonder why Lupin just doesn't seem to care as much? Sirius sends 
Harry birthday presents and invites Harry to live with him, so why 
doesn't Lupin? I understand that the latter would probably be 
impossible considering the werewolf problem, but would it be so hard 
to send Harry a present? And just one more thing.. was Lupin ever a 
bit miffed at James for making Sirius best man and godfather to 
Harry? I have to say that if I were in his position, I'd be a bit 
jealous.
