Should I call him back?

My ex boyfriend called me last night to see if me and my friends were still out and then i said no im back home now and he kept chatting asking why I had said things on facebook about him like I had posted lyrics on facebook, taylor swift ones. And he asked why I did that and he seemed a bit rage and I said look im sorry and he kept wanting to chat but I said I had to go and I went to bed and I woke up with 10 missed calls from him. We broke up 3 weeks ago and he said he hasnt mentioned anything about getting back together. Should I calll him back and asked why I have 10 missed calls? He was drunk.
