Advice??

So I’ve really liked this guy for a while but then he started liking my friend so I got them together cause I want them to be happy with one another and I’m kinda jealous, they don’t even talk and everybody thinks they are gonna break up, my other friend says tell him, don’t tell him or tell him after they may breakup. I don’t know what to do, and if I told him it’s not like he likes me back, please help
