Is he really busy or ignoring me?

I met this guy few months ago and we hanging out together for the first time it was fun and video call for hours but after 2 days I texted him like "hey how are you?" And he replied me after a day he said he's very busy, I said it's okay I just wanna do video call again and he replied me after 2 days he's very busy but he's interested too, what does it mean?
