how would u react?

The ex talk could be specifically to try and figure out if you are into him, obviously if you consider him a romantic prospect it will make you a little upset. As for biting your bag, I have no idea, but did it seem flirty to you? Does he initiate any touchy contact or just looking over your shoulder and butting in to your work? If he does touch, where?

 

Hmm, so far I do not see any flirtation signs based off of what you reveal

 

What's the age of you two

 

Not enough to fully say he is flirting unless he is staring at you with love eyes, or he seems fidgety around you. Looking someone in the eye while conversating with them is a pretty normal sign, everyone should look a person in their eyes when speaking to them, it shows you are focus on what they are saying. I would keep checking out the situation and see if he gets more hands. Does he know your sexuality?

 

You could always try initiating very light touching to see if he responds in kind... would certainly help a lot more than just glances and looking at each other.

 

Back when I was single, I would have dealt with this by taking a nice long look at his mouth then making eye contact. A lifted brow and a subtle grin would complete the look and make it clear I'm asking if he's really hitting on me or not, and that I'm open to it if he is.

I've always found body language to be extremely convenient in these sorts of situations.

 

Focus on his eyes. Eyes tell more than language ever will.

 

How do you raise one eyebrow? Like, I actually can't do this so help appreciated...

 

He should lol.

 

I learned from watching The Rock on wrestling lol.

 

He actually bit your school bag? Initially, I assumed that that was a typo and that he 'hit' your school bag.

 

I never really went out of my way to learn it, so much as I picked it up from someone I knew. I suppose you could teach yourself in front of a mirror, though, with enough practice.

 

From what you've written, it seems that he's just being playful and cheeky (biting your bag). Of course I don't know either of you in person, and cannot see you interacting with each other. I think once he knows your sexuality, he will either be more cautious of sending signs that he may be interested in you romantically, especially if he doesn't feel that way about you, OR he could be more deliberate. Do you guys hang out outside of school? What's he like when it's just the two of you?
