Even though you guys broke up,maybe he still wants to keep in contact even if he broke up with you. Some people likes to keep in contact with their old relationship partners.
Why Does My Ex Still Want To Be Friends With Me He Dumped Me?
He still likes you that's why .....and he probably feels bad for dumping you and he thinks it was a mistake .....so now he's trying to show you that he still wants you with out asking you out
He might just see you as more of a sister then a significant other...
