Does he like me if he introduces me to his friends?

We met in the gym few months ago. In the early days we met at the entrance to the gym one of the times I stopped I looking at him for a few seconds he winked I swiped the card to the entrance looked back at him he winked again. We'd stand close to each other a lot. Now we have each others numbers. Had his email first , he asked for my number instead. I walked by the area he trains one time I heard "there she is" from his friends and another time I went to look for him his friends where there said hi and when I turned away heard "oh she came" . He helps me on the bench press I text him when I'm ready he usually comes up close behind me leaning in or trying to scare me. He grabbed my hands before on the bench press putting my hand in the right place like no let me. In between sets we'd be talking we'd look deep in each others eyes. He started walking upstairs after asking if I needed to get my stuff saying let me walk you or I'll walk you. On instagram he posted a picture on something he did I dm'd him congratulating him after he replied back to me as soon as he saw the message. Other people who commented under the picture I noticed he didn't reply to anyone else until the next day. It seems like he might be introducing me to his close friends? today he helped me with bench again he came up behind saying boo. In the bench area one of his closest friends were there he kinda introduced her to me. Calling her over saying my name and we both said hello to each other. And he seemed to bigging himself up in front me. Does that mean he talks about me to his friends?
