Not a threat. It's a good deal.
Either way the child will be taken away. So go w baby daddy and be in the kid's life. Or wait til there's a court order to have him be taken away completely.
He's quite selfish for having out the child thru the wringer w/ low grade quality or barely effective meds or effective but strong side effects when he CLEARLY could have gone to the source. Plus, with him working like crazy it's gotta take a while lot of toll on his body and mind. If Ian hadn't come. He'd had probably continued on the same path. Doing a disservice to them BOTH.
I understand it's a good deal but you do know the first meeting after so long left a bad taste and also he could directly said this before and didn't have to create unnecessary problems.
Threaten his child and then propose marriage.
