Help me please he confuses me soo much?

He confuses me so much. He asked me to hang out 4 times but whenever we do he'll always bring one of his siblings or some friends because he gets nervous (he told me this at the movies.) Anyways we've gone to the movies 3 weeks in a row and the 1st week he kinda made a jerk move because he also invited our friend who I think he also might like. They were mostly talking so me and him hardly talked. Then when he was taking us home he asked if he could be one of her models (she's going to school to cut hair.) He has flirted with her before in front of me and he took her out to dinner before (but he brought his siblings too.) But the thing is he also flirts with me. He has told me that I looked nice a bunch of times, that I have nice eyes, he has a nickname for me, and teases me for being short. Plus he likes to touch me a lot. Also he works with my dad and my dad says he asks about me sometimes. He doesn't do all that with her like the only thing he does is tease her for being lactose intolerant. And it seems like he likes to give her rides to places but not me. By the way he's NOT a player because honestly he's way to shy for that and he's a sweet Christian guy. So why would he do all that stuff if he likes her?
