(S6 E2 The Illustrhater Spoilers) Why do they do these things after so long???

Why is Marinette back to not being able to engage in simple conversation with Adrien???

Didn't she date him for months prior to this episode, and even gradually learned how to talk to him in previous episodes???

She does not seem to understand the things basic couples do, and even one of things she does in the episode is just holding a leg up in a certain way, that's not just a couple thing, anyone could do that.

If this keeps up, I would suggest to Marinette if she were real to just, avoid dating, as it is clearly too much responsibility and work for her and she should just relax and focus on her health and well-being as a person and as a guardian of some of the most powerful objects in the universe.

Adrien also isn't off the hook, he is very spineless, after everything Marinette does in this episode, he doesn't try to ask her what's wrong, or why she keeps flaking on him?

He just gives up his relationship with her because he wants to please her???

Again, if being in a relationship is too much responsibility and work, than I would also suggest that Adrien not date as he is also unwilling to protect his long-standing relationship with his girlfriend over a few hiccups, (not that those hiccups are his fault, just that they don't feel like something to end your relationship over).

But what do you think about their relationship in this episode?
