It's an Invisible Wall

I've thought about something while listening to a song from Julia Fordham. It's an invisible wall, Julia said. Then I heard my own thoughts saying... People say that it's easy to fall in love. But why is it hard when you're already there? And why is it so impossible for two people in love to have a seamless relationship? So many questions running around my head right now. Still no answers but more questions are popping out endlessly.
Someone close to me said, " Don't be a good girl anymore, we're way passed that for years now". Thinking about it, I know she's right. Deep down I feel tired of being someone who is  just accepting and not asking for more. And I know I deserve more. This in return results to an invisible wall that's building between us. It's slowly tearing us apart.
Another thought... "What if I just simply walk away from you and never turn my back again? Be the bad girl and never explain why and just walk away. It's this invisible wall building up that's making me think this way. If only I could just scream at you and tell you that I want you, I want more of your time, your love, and everything more than you think I need. But can you understand me at all?
