Since this topic is about a cPTSD person in your life it has been moved to When Someone in Your Life has CPTSD (http://outofthefog.net/C-PTSD/forum/index.php?board=12.0) where hopefully other members who are dealing with similar issues may spot your post easier and give you advise and support from their own experiences.
Perhaps in that section you will find other threads dealing with similar situations as well.
