so he offered a "compromise" and then issued conditions on that compromise he decided could not be satisfied.
I smell a rat.
Who cares? Even if he had no intention of renegotiating the contract and was only pretending to consider it in order to not look like so much of a dick, it doesn't change the fact that they had a legitimate contract and his consent was required to either alter the contract or let her implant the embryo.
I'm having a hard time caring about this. It doesn't bother me that much if a contract gets altered because the situation on the ground has changed. Businesses do this to each other all the time.
