I love my best friends girl friend
Why would you love your friend's girlfriend?
Because they are madly in love with each other. It's just that she is not confident about their relationship
It is a bad idea to to get involved with the partner of your best friend. It would be difficult to keep that friend if you were to act on the love you feel for the person. Would most likely be the better option to not intrude on the relationship of your buddy.
That's a very selfish and foolish thing to say.
I just don't think you should be interfering with your friend's relationship. You should just leave them both alone.
