OMG...What a sad sad story! My heart absolutely breaks for that little girl who has this miserable short life ahead of her.
In terms of what was done - although I can see both sides and abortion is certainly not something anyone usually wants to do, but the contract did cover this circumstance and the parents wishes have been honoured. I can't imagine being in the position where some rogue surrogate is running away with my baby?? yeeesh what a horrible mess and no one has come out a winner!
