Inlove84,

I can't come up with any book titles right now, but I wanted to tell you I sense from the things you say that you do not think as well of yourself as you should, or as highly as your fiancé thinks of you. You were there for your sister when she needed you, you were happy for her happiness, right? You gave her space when she needed it. You deserve that and more. Think about that. Sometimes in life we need to put ourselves first. Looks like this is your time to do that. I am a middle child too, I know the struggles. I wish the best for you, you deserve it.
