Bad friends

Harry needs help and is sent to Canada to get it. He comes back confident and more happier, but he finds out that Ron has been using Compulsion and Amortentia on Hermione since her sixth year and raping her whilst she is in a comatose state, she's ends up pregnant by force and doesn't know she has betrayed Harry, so she loses her grip on sanity and ends up in the ward in St Mungo's
