Boyfriend help? jealous of his 'perfect' friend?

I would do the same thing and I have. Meet this girl and see for yourself and then tell him that they can be friends but that he needs to lay of the compliments and you may still be really jealous but if it makes you feel better you can kiss him in front of her. It's kinda rude but it sure made me feel better. If you need then talk to her one on one and ask if she likes him at all.
