I have a crush and idk what to do

Please don't be rude.

So basically it's the first time I really like someone.
He's my coworker, we work in a restaurant.
I first saw him months ago in the university cafeteria and recognised him when I started working.
He was indifferent to me at first, but with each passing day I started to appreciate him.

We started joking with each other and even "flirting" with flirty questions and sentences.
One time he asked me when we were gonna get married, one time told me that he's jealous if I get a boyfriend, he started touching my hips to annoy and tickle me, one time he bit my arm when we were playing around.

But he gives the playboy vibes that likes to joke around like this and make girls fall for him, so I started to not care much about him.
But one day, I really don't know why, I started to see him with different eyes.
Despite not being my type, I started to like his looks, his voice, the way he speaks, the way he laugh, his stupid side, confident side and the way he's effortless smart.
I think I started to like him, but everything came to an end when I realised he doesn't want a relationship, he wants to sleep around, have fun, stuff like this, things that I don't do.

I talked to my other coworker, which is my friend and his, and he told me to give up cuz he doesn't seek for a relationship and that I'm not his type. Understandable, since he seems the classic playboy who likes those pretty girls.
The way I hate these kind of guys is unspeakable, and I don't even know why I fell for him even after this.

One time he drove me home (usually he takes home me and our other coworker, but that night he told me to go with him only) and I asked him about a personal experience in university and we made car rides while he explained to me and gave me advices.
This ended with me telling him that I thought he was more shallow, and he told me he's not, that it's all a mask.

So I really don't know what to think.
I think I like him, but I might have romanticised him too much.

Again, please don't be rude, I know some will say to just give up if he doesn't want a relationship, and I know, but I still want to know what you think.
