Ex contacted me out of no where.

after leaving me; calling me a snake, a person who ruined his family, an immature child, a person who can't think logically, a selfish bitch. Basically telling me to fuck off after asking for my things back. It's been a month since we broke up. I got a new phone, changed my number... didn't give it to him. Blocked him off all social media.  I am planning on pursuing my dream to go to the Air Force. And out of no where he makes a another twitter account and tells me to come outside of my house. I said I am not home and he's like where are you? and I asked why? he's like never mind. He's the one who wanted to leave me, I am not going to take him back. What's his deal?? I am gonna make something of myself and move on. If he wanted me... he shouldn't have did me wrong like that. I did nothing to him.
