Evan had just broken up with his girlfriend after a really bad argument, which ended up in her crying, accusing him of cheating and then just breaking things off. Honestly, he didn't understand shit at first. It all happened so fast- when he finally came into realisation, he just accepted it although he was sad about it. But he wouldn't show it. He was too much of a proud asshole to show any sort of weakness. But his friends weren't stupid. Which is why they were trying to set him up.
