Dude, first of all, you cannot make an artist do anything you want. They are allowed to do whatever they want with their comics. Second, Inter Schminter isn't even finished yet. Can't call that a sad ending now, can you? Third, what relationship DOESN'T have arguing in it? I've never been in a relationship with anyone, but even I know it can't all be sunshine and rainbows. There is nothing wrong with adding a bit of conflict between two characters.
