Why would be so childish?

So, I said something on facebook and obviously my ex boyfriend feel offended about it. This is what I want to say to you, ex boyfriend:

If you feel offended about what I said, grow your balls and talk to me in front of my face instead of remove me from facebook. You are soooooo 2008! I couldn't care less. Grow the f up!

This is the second time he removed me from facebook and I suggest him to grow his balls or wears skirt. That's all I'm saying. Don't be such a bloody coward. Talk!
