What do you think about this type of friend?

She loves to be with me. We always have loads of fun together. When she is stressed she shows it sometimes or puts up a wall then has breakdowns later at home. She says she loves me (in a platonic way). Hugs me a lot. We see each other everyday. Doesn't have the best family relationship like I have. Is nervous to talk to the one she likes even tho I talk to him all the time and I know that she likes him. I say she is pretty but she always disagrees. I just want your input on what you think of this friend of mine.
