Ever so slightly annoying behaviour from friends?

Your friends are acting completely immature! Yes I think you should tell your friends that they scared him off and you're kinda pissed at them, and in the future, would appreciate it if they butt out of your love life. I also think that you need to keep your mouth shut about your love life, because you now know how they behave, so as much as you may want to dish about an amazing date you had - find someone else to confide in. And I have to say, I'm a little confused as to why someone who is 22 is friends with a 17y.o.
