Are you worried about what your brother would say or the fact that you're moving on to someone else so quickly? You might be looking to replace your ex with this boy which would explain why you felt so close so soon. I always suggest a bit of time alone after the break up of a relationship to reflect on what's happened and figure out where you want to go from this point. If you have so much in common with him its not going to change much in the future and if you still connect after a little bit of time has passed you'll be in a much better frame of mind to start something new.
Your brother might be a bit uncomfortable at first if you start seeing his friend as some men tend to put people close to them in catagories and don't like them to mix, but will eventually come round when he sees how happy you might be together. Good luck!
