He's taken but we like each other

Okay so a few months ago me and this guy really hit it off but he has a child. (Which I dont judge at all ) but I didn't really wanna deal with drama so I rejected him. Saw him last weekend and we hit it off again but he has a girlfriend. And I'm really sad because I actually like him this time. Do I just stay friends or leave him alone. What would you guys do!? Because I really like him and I'm confused
