::Clarification:  
 ::*Rigby had both a wife and a girlfriend in the military.  
 ::*The child is the child of the wife, who is referred to ambiguously in one of the cited articles as "partner".  
 ::*Wife, not "partner" (as in girlfriend) lived with child. 
 ::*Wife has stated that she and Rigby were "looking forward to continuing their lives together".  This appears to indicate that the marriage was "permanent" and the "separation" due to circumstance.  
 ::Let me stress that discretion is needed.
