I respect a surrogate mother, but the truth is, an agreement is an agreement regardless of whatever has happened.
If a person is unable to control their feelings, they must understand that this situation cannot be lived by them. The baby will not belong to the surrogate mother, and there is no right to regret involved in this matter.
It's true, the surrogate mother has no right again as far as an agreement has been made and depending on the agreement regardless of the feelings attached to it.
