My 18 year old daughter is faking a pregnancy while she is actively trying to get pregnant. She's not particular about who she gets to father the child either. On her 18th birthday she ran away from home (not packed and moved out - ran away with the clothes on her back). I've pieced together that in the previous months she began associating with new people - very disreputable people, mostly men. She fabricated a whole new life history. Multiple children up for adoption, several abortions / miscarriages, drug abuse, alcohol abuse, criminal record, abuse by me, that I was in prison for drug charges. She had also began trying to get pregnant for several months. Her main boyfriend was in juvenile jail for assault and molestation. She left him when she thought she was pregnant but, a recent evaluation for a mental detention warrnat (not approved because she wasn't suicidal) determined she was not. She immediately went back to this guy telling him she was pregnant. She was active in school, sports, and church. Now she rarely speaks to anyone involved in her former life. Also of note, she was severely abused by her biological father. She has now embraced him and his substance abuse life style. I realize that she probably has several different issues going on but, I'm baffled by the sudden change. She had several brief episodes of this behavior between 16 - 17, but she has been stable and seemingly happy for a year and a half.
