I also saw it this way. I loved how Amy and Rory communicated via expressions and checked in with each other.

Interestingly, Karen Gillan said, in DW Confidential, that Amy's a flirty person and therefore she would be cool with Rory being flirty. Arthur Darvill was more on board with the jealousy theme. It's quite interesting to see what the actors intended/thought they were doing. I think how people respond depends on how they already judge that character. <3 my Ponds.
