For goodness sake. You have been provided with a glowing real-life example of exactly how little this man actually cares about you. He's even said it himself. He doesn't love you, but he'd quite like to keep shagging you as long as you get rid of the inconvenient baby so that he doesn't have any obligations.
He's foul. Scars or no scars :(
Look, you do not want a termination. Which means that you would be a fool to have one. Never, never have a termination for someone else's sake. It doesn't work. You'll hate him for it, or if you're sufficiently cowed to not let yourself call it that, it'll express itself in depression and unhappiness which he'll find tedious and finish things any way because you're 'no fun' anymore.
You want this baby.
It's your last chance.
Your DD wants a sibling.
The bloke you're potentially getting rid of the baby in order to keep has told you he doesn't love you anyway.
Keep it.
My prediction is that Shitty Man will hang around anyway!
He'd prefer not to have the baby so he's trying to bully you, but if you refuse he'll probably skulk back before long anyway.
If you're not going to ask him for any support, that's fine. Tell him that, tell him you're keeping it, and you're perfectly ok with him still sticking around, but just like your DD, this baby is now your child, and that's that.
