Should I back off?

I’ve had feelings for this guy for a few months and he knows I like him. I’m almost certain he likes me too but he hasn’t made any moves but we’ve gotten a little closer recently as friends and we flirt quite a bit. Since he knows I like him, he already knows he has me and I feel like he likes the attention. If I start acting more distant or less interested, will he begin pursuing me? I’ve decided I refuse from now on to be the sole pursuer in this situation. Or will that drive him away?

My friend told me he’s acted jealous when I’ve talked to other guys and he always asks/talks about me.
