my guy friend got dumped

This guy I used to like got dumped by his girlfriend on like, Christmas Eve! 

He used to take forever to reply to me, but now he starts replying pretty quickly. His girlfriend dumped him I think because he used to take soooo long to reply. 

He only really started considering other people's feelings after she broke up with him! Unbelievable, can't believe she stayed with him that long. I don't want to date a guy like him.
