Did I tell you I'm jealous of my best friend because a girl that rejected me started texting him?
I can understand why you'd feel a little jealous.
Yep, it's a real bummer!
You should try not to be jealous of your friend, sometimes that's just the way the cookie crumbles. You could let your friend know and kindly ask him not to share details about their relationship for now.
They might not ever get together. Either way, you're right. I should just move on.
I'm glad you see it that way. There's more than one fish in the sea. Besides, you never really established a relationship with her.
