Why is he acting like this?

This guy, I’ve been speaking to for 4 months but we haven’t met but was going to. So we planned a date and he was being a bit off after so I realised (my mistake, and I regret it) I lashed out at him and said I don’t wanna see him cause it feels like he doesn’t wanna see me. So the he’s like “how don't I wanna see u when I’ve given u a date?” So we just argued and I regretted and said to him I still wanna see him and he was like u just gonna keep changing ur mind? And before I can answer in the morning he removed me off his Snapchat. I then messaged him on Instagram asking why he did that and he was like “look at the way u acting yesterday saying u don’t wanna see me wtf.” So I tried to explain and said I overreacted. He wasn’t having it. So I left it and gave him 2 weeks space. I then texted him again “hey how’s you?” He responded very fast with “good thanks you?” And then I replied and it’s been 4 days now he hasn’t even opened my message but still follows me on insta and watches my story. I posted a guy on my insta too and he was watching that immediately. And he would if removed me off snap if he didn’t want anything to do with me.
