I agree w/twinmom. Unless you are court ordered to provide those documents, he can very easily get that information form the SS Office and the county records department. Now, he may have to pay a fee at the county records department for copies of the birth certificates, but hey...he's got money for a divorce, he's got money to pay for birth certificates.

Again, I do advise that you make copies of the birth certificates just in case something happens and leave the originals and the copies w/someone you trust. You can't always trust the MLCers for being upstanding citizens.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
