Women: Do you verify the claims of your ex's?

This ones for the fluther-chicks. Do you actually care enough to verify claims that your ex makes. Verify as in ask around, or search on facebook.

Claims of a new girl for example.
Claims of things the person has been up to as another.
Just claims in general.

Assume that you still care about the ex. Assume the relationship sucked and you don’t care about the ex.
