Why is my ex tormenting me?

My ex and I broke up three months ago; yet he still texts me saying "what's up?" The first time I replied all he did was talk about his new girlfriend. So, after that I ignored all of his texts, but he still keeps bothering me. Why is he doing this?

He was the one who left me for this other woman; that's why I don't see why he's bothering me.
