Sorry if I've missed this in the past, but is WAW aware of this? If she is it does sound very dangerous.
OM's mom told him that she met met w/me once after she figured out who his GF was (he's D'd), so I'm sure that WAW knows about that but the communication b/w OM's mom and I has been clandestine since then. We both play our cards close the vest and are careful not to act on info we share.
