What.. Does my ex like me again?

It’s not that long, so help me out a little, please? :)

Okay, so we went out for about 7 months and we were both each others very first love. Now he has a new girlfriend for about a month now, and I’m just single and having fun. (But I still like him). The problem here is that he is a very committed person and would never flirt with any other girl while in a relationship, but lately that’s all he has been doing, flirting with me.

He considers typing/sending smiley faces, flicking, touching, taking pictures and texting with other girls/guys is flirting. But all of those that I mentioned, he’s being doing that to me every single day.. and I have no clue what this means! Does he like me again? Is he scared that I’m moving on?

-playfully hits and touches me in class- Me: “I know you want to touch me and all, but all you gotta do is just ask!” Him: *laughs (All he does is laugh. He doesn’t even deny it, so that left me kind of confused.)

Am I looking into this too much? Or is there actually hope for me? and please don’t just say “Get over it!” or “Move on!”

Oh, and he’s the type of guy that wouldn’t try to get into a girl’s pants. We have been through a lot, and I know him quite well.
