Love Like You Explanation

If I could begin to be, Half of what you think of me, I could do about anything, I could even learn how to love. When I see the way you act, Wondering when I'm coming back, I could do about anything, I could even learn how to love like you.

I think I finally understand what the lyrics mean. It’s rose thinking of humans and how she wants to become them. When she meets Greg she notices how he thinks that she is great and that she is initially a human. But in tonight’s episode, it is revealed that he no longer thinks that she is a real person and an actual alien, and that she does not know the meaning of love. As he tries to fuse with her, both of them realize that were meant for each other. By the end of the song I think it’s rose’s way of saying that she’s going to become half of Steven and doesn’t know when she’s coming back. But since she’s half and half, she may even learn how to love for real.

That’s just my interpretation at least.
