We broke up on bad terms but was my reply back fair?

After his ''Oh you're not ready for commitment'' statement with a mocking tone, this was my reply:

Well then you're not ready to ever be a real strong man and never were. You're a cowardly little girl and you're small. I had to fake it the whole time (I lied on that part). You suck too. I'm now demoting you to blocked ex boyfriend.

Who the hell he thinks he is to dictate when I feel ready for something or not. I was hurt, super furious and so I replied back. Was my answer fair?
