I think even in the movies as Ron and Harry were whining about dates for the Yule Ball, Snape was pissed. Like he knows these little shits have a great girl but they'll make the mistake of not asking her out. Even Snape probably knew what was up. :/

God, Harry and Hermione just deserved so much better. I mean if my boyfriend ditched me in the wilderness (I know part of it was a Horcux talking but he could have come back the next morning) I wouldn't keep dating him, much less marry the dick. 

Hmm hopefully this is the cringeist post for you and then it'll be smooth...er sailing.
