It's a blessing of Allah (SWT) that He has gifted you such a nice and intelligent friend. It's really nothing to worry about if she talks too much and insists you listen. This habit of her will be changed when she realizes the importance of listening to others. You can gift her some books or magazines in which this personality trait is focused. You can take help of your teacher. You tell her to advise her to realize the importance of listening as Allah (SWT) has gifted us two ears but only one tongue.
