I'm new here and at my wits end.  I'm really not familiar with all the abbriviated lingo but will give it my best shot.  I have 2 bio kids and 1 SD.  All are close in age and all are married and have thier own homes.  I have raised SD since she was 11 and she is now 34.  In the beginning I thought it was all good, Ex was not involved because SD didn't want her involved so at that time I didn't have to deal with her.
