Answer 1:

Hey come on.. Give the guy some space and a break.
Hes propably still freaked out that hes dating some girl he met online.
Sometimes it takes us guys a while to get used to changes.

Answer 2:

The way a person interacts online and in person is actually a very big difference. And it could be that your not the same person that he thought you were. But if hes not a "ass" he will tell you.

Hope things go well for you.
