Is he in to me?

So backround story…

 He "liked" me at the beging of school but I only liked him as a friend. I started to like him more the more I new him. I foud out that he had a girlfriend and was suppotive. The girlfriend dumped him for a verry stupid reason (lond story).  I "like" him a lot now and wanted to be his girlfriend, On some days he would say now that I'm single I can date whoever I want. And I'm glad I'm not dateing her! 

End of backround story.

So one day we finished up with our lockers at the same time and walked together alone. He said to me “ Now that I am single I can imagion dating anyone including you, and that I am 10x prettier than my girl friend” Then I totaly blew it I said thank you and you’re so nice. Then the next day I was going to tell him that I liked him but he seemed like he wasn’t that in to me anymore. I want to date him is he in to me?
