<human>: This started like 2 months ago when I attempted to talk to this girl  [17F] who goes to my school, however I repeatedly got shutdown and the conversation petered out. My friend [17M] , however, really hit it off with this girl and have been talking for quite a while. I suspected for quite a while that this girl liked my friend and resigned myself to the fact that I wasn't going to make any progress.

Recently she finally professed that she liked my friend and at around the same time my friend told me that he had liked her. Very stereotypically high school I know. However he now refuses to do anything about it despite my reassurances that I don't mind, and constantly reasserts that he thinks I will just be upset if they get into a relationship. I honestly do not mind and want the best for him. How do I convey this to my friend?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I pursued a girl, got rejected. My friend liked her and is later asked out by her. How do I tell my friend to go for it?
