is this normal or is there a name for it?

thank you so much for all your replies it has helped me a lot esp 44294 julious,if possible can you get bk in touch with me again i realy found your advice very helpful & passes it on to my son ,who is sadly still at this female,s beck n call!! i really dont get it atall,the part i hate most is her calling me & telling me all what she has been up to behind my son,s bk,this torture is affecting me realy bad i recently had a nervous btk down i was in hosp for 12 day,s,in ans to those who say keep out of it trust me when i say i have tried my hardest to no avail,i truly believe they both get a kick out of hurting my family!they both involve the family in different ways be it he or she has been picked up by police while drunk,then she thinks its ok to tell him the men she has been with & so on it contiues!,my fear is 1 or both of them will end up dead!!,no amount of listning to my son then helping him get bk on his feet seems to help him ,he throws it bk on my face as soon as she comes on the scene again i just pray that 2012 will start afresh my son is home at this time for how long i dont know,thank you all for your replies & a happy 2012 to you all best wishes CBM
