Guy's Behavior

I need some advice?

I can’t get over my crush I just can’t I have a gut feeling he likes me even if he gives me clear signs he doesn’t seem interested. He will never text me first but answer to my questions when I text him. He will never like my posts on social media but will like all the other girls posts. In person he doesn’t talk a lot but I feel he’s comfortable around me. He won’t really talk about personal stuff and shuts me off if I ask anything about his last relationship but that’s pretty much it. He does give me other signals as well he started at me when he thinks I’m not paying attention, he shows off cars he’s driven, stuff he bought, during a scary movie I grabbed his hand and he just accepted it and held my hand back I don't know why I can’t get over this person. I even deactivated my Instagram so I don’t post stories he watches all my stories 100 percent of them.
