I agree. I'm so scared about the following chapters. I can remember a couple having a problem like this before. They really broke up but the good thing is they're back together (10 years now) but it took them 2 years to get back again with the help of their friends.
i'm crying like seriously i'm so glad they made up but what the hell's up with that foreboding message at the end????
