That's called manipulation. He's manipulating and controlling you through threats.
"If you do XXX, I'll do YYY."
So you do XXX just to prevent him from doing YYY.
It's all manipulation.
If you give in to that it just gives him more power over you. You have to look out for yourself. What are you becoming and do you like yourself for it?

Why does the daughter has to suffer under your relationship? That's a weird threat. I think he was thinking of doing this a longer time because either he hates his job or supporting his ex, but because it sounds so drastic and is afraid to loose you he uses it as a threat because he's desperate.
You should still breakup with him. He could be bluffing and if he loves his child he won't abandon it. It's also not really your business what happens with his child and ex, even though it feels like it.
