Inconsiderate piece of shit

When your soon to be ex-girlfriend tells that she's leaving you because she now suddenly feels disconnected with you while you have absolutely no clue what has been up.

Her: I'm leaving you because I don't feel the same with us anymore. Thank you so much for everything
Him: Seriously? You're leaving me without any hesitation or chance for us to figure things out? Well you're welcome you inconsiderate piece of shit! Now fuck off will you.
