I'm confused, just because Marten and Dora have one fight it is like omg it isn't worth it anymore.
people do not break up over girls being insecure, especially not if it happens once in a harvest moon in July. (doesnt happen that often)
seriously i doubt Marten will call it off just because Dora gets insecure about other girls. If anything it is cute.
as for the honeymoon period wearing off theory, i seem to recall very recently a very in depth mar mar speak conversation
if that doesn't indicate that things are going pretty well then what does lol
ANOTHER POINT. they are sleeping in teh same bed, trust me if a girl was REALLY upset with you, you would not be in the bed, especially if you didnt live together lol
