ex reached out after two years?

My ex is a narcissist, had a girlfriend they broke up, now he reached out to me 2 years later? 
He messaged me on IG saying, "Payton you remember me?" Then the next day "Can you call me about something?"
I responded today saying...
" you can call me at 3:45 when I get out of class."
He calls me I answer then he hangs up.
I call back no answer.
He calls again and he just asks how my life is going and what's new. I said it's been two years and now you ask me? I'm doing really well... Told him about school. He thought I was being nasty I just said you did some nasty things blah blah. We were ok and hung up. I told him "don't take this the wrong way but next time please don't bother asking how I'm doing. I moved on. So unless next time it's something that's important please just respect me space." 
He tried to guilt trip me and I said you'll never see what you did, he said he wanted to apologize and I said why didn't you?
He didn't answer, kinda up in the air rn 
Why would he make it so dramatic ?
