At the start Erica tells Mark

"But you’re going to go through life thinking that girls don’t like you because you’re a nerd. And I want you to know, from the bottom of my heart, that that won’t be true. It’ll be because you’re an asshole."

At the end Marilyn tells Mark

"You’re not an asshole, Mark. You’re just trying so hard to be."

When Mark waits on the reply from Erica and continuously refreshes the page, does this indicate that he believes that he can discount Erica's insult to him?
