FISCAL,
There is an easier way than all of this over elaborate planning and scheming you are contemplating.
Simply sit down and talk with the mother of your child. Tell her the straight truth. It will accomplish a lot.
You will feel better and she will know what she is working with. Anything less and it would be fair to question your worth as a person.
This is the mother of your child and your child sir ... They deserve your honesty and sincerity ... regardless of how she acts or behaves.
My God man!
