I think I loved you is the saddest thing you could say to a person because it still hints to you still loving them but the person changed in a way to make you be weary of them it portrays a tone of betrayal and heartache. I never want to hear somebody saying that to me. That they loved me. It's always possible to rekindle emotion for somebody but keep yourself at bay because you think they've become a monster or a hazard. The sentence I loved you is truly a heartbreaking one.
