How do I get over him?

What are you, 10 yrs old? From what I can decipher you were dating for 3 days and you couldn't even ask him out yourself. If you're still at the age where you need your friends to ask guys out for you then I seriously doubt it was heartbreaking. Rent a chick flick and buy a huge load of chocolate and chill with your mates. You'll be over it before the first movie finishes.
