Bam Margera's wife has tried for years to make things work with her estranged husband, but has apparently decided there's nothing more she can do ... filing for legal separation.
Nicole Boyd filed separation papers Wednesday in L.A. citing irreconcilable differences as the reason for the breakdown in her marriage with Bam.
