Ex rubbing rebound in my face?

Anonymous
Okay so he told me himself he was seeing someone a week after we split the last time from our on/off period. We was arguing & I said some hurtful things (which I regret) and he turned around and said well the girl I'm seeing doesn't seem to think so. He then rubbed in my face how she was perfect & they had an amazing connection. But still went on to say he missed me & hasn't replaced me.

Since then he's been posting things all over social media rubbing there relationship in my face. Now I've know him for 4 years, been with him a year and a half and I know for a fact that it's all an act. It's so out of character for him.

Firstly he doesn't publicise his life on social media especially his love life.

Secondly he's emotionally damaged & would never rush into a relationship.

Now we've been in NC for a month, he had stopped with the flaunting for about a week and a half, but as soon as I post about some happy news in my life he starts it back up again. Why? Why is he doing this! And why is he forcing his relationship down my throat why I choke on it? He ended it with me, I could understand a little bit if he was the dumpee but he isn't.
