How am I getting this so wrong?

Okay so context I am a shy girl, I do the usual of going super quiet especially when I like a guy and then I don't know how to act around him so get it can be difficult to read.

I was out with a group of friends, during the night my friend met up with her cousin and her friends, there was a guy in the group who was drop down my dream guy during the night I saw him looking over at our table and making eye contact with me and smiling. I presumed he was just being friendly

Later in the night as we were all leaving his friend (who is also a girl) shouted across to say I was gorgeous and he was with her. As we were leaving he hung back and walked across with me. We didn't say much together. I walked in behind him and he held the door for me, a guy came into my face to chat me up and he was holding the door for me smiling again. As we went into the bar he stayed standing near me by the wall while his friends went to the bar, again another guy came up and he smiled again

Throughout the night I would keep catching his eye but he never once tried to make a move or talk to me. (Sorry this is so long winded)

I'm not super experienced with guys and because I'm shy I really struggle with reading if it's just me feeling a vibe in my head, I'd love to force myself to make a move especially with a guy like him but I just want to be able to read even some ques that I am missing right now. Any input or insight would be so amazing- especially if he was sending signs of interest or if there are actual signs to look for and advice on what to do in the future.
