Am I a bad friend?

Ok, so, there's this guy I REALLY like. I like him so much, I might be actually in love with him. I've known him for...I don't know, I want to say 10 years. And my friend, Kaira, met him two years ago. Well, they've been getting really close lately, and he's been totally crushing on her. I feel like a horrible friend because even though I'm still really nice to both of them, I have this horrible jealousy building in the pit of my stomach. She always asks if I think they would make a cute couple. As badly as I want to say no, I always say yes.

Am I a bad friend for lying and feeling so jealous?

no because you dont want her to get mad at you so no

well this is where you have to pick a friend or a lover. which is more important to you? and, if he is not interested in you in that way and you try to pursue something you might hurt your friend.
