i think before the married woman accept the gift,she must ask for her husband's consent whether to accept it or not because when the husband finds out that she accepted a gift from her ex without his consent,he marriage might be at stake then.
its not an issue of consent..a married women should neve have any kind of perceived contact with her ex..this is somebody u shared intimate moments with in the past..it will be the begining of trouble..it will give an impression that this woman still has eyes out there..listen ladies if u want to have a happy marriage disconnect yourself from everybody that used to be your ex..avoid them like a plague...there should be no friendship at all..if they are coming from left go right.. any attempt to remain friends will end in disaster....
