Thinking on the past, and the true reasons things happen.
I'm not going to go into this much, but if you want, I'll tell anyone who asks in person. Fear is a terrible thing, especially the fear of being alone. It can make us do crazy things, and it more than anything else can cause us to hurt ourselves and the ones we love without ever realizing it. Can we repent for the pain we cause, all for the sake of having a light in our darkest hour? Is it a sin to want to love so badly, that you are blind to another's true feelings? Who is to blame when fear is the impetus for harm? I don't know. When you say you love someone, mean it. Love is too precious to be a lie.
