If he showed up at my house unannounced... what does that mean?

basically i've been ignoring my guy friend/ turning down his messages when he asks to hang out because he did something really shitty to me. and yes I like him. I thought he liked me as well bc he showed signs, but maybe he doesn't (hence why I'm mad at him... long story but I won't go into details)

Anyways I texted him I was busy and couldn't meet up, and within 10 minutes he just showed up to my house and started knocking and texted me that he wanted to talk.

Did he show up to my house bc he sees us as a couple or bc he likes me or bc he actually has NO respect for me? I'm confused on how to read this situation
