I have a 21 yo daughter and 15 yo daughter from my first marriage, and have a 3 yo and 4mo from my second. My oldest is the problem. During her teenage years she unbeknownst to me, had a cocaine addiction. I say unbeknownst and admit that I was kind of a absentee parent during those year dealing with my divorce. I was there physically, but not mentally. She kicked the habit on her own, turned her high school grades around and graduated. She is currently going to college online and working during the day. From a really young age, she would steal things and lie.When we would catch her, we obviously would punish her. It kind of stopped until she got older-maybe 17ish and then we would notice money missing from a wallet or purse. We would confront both girls, punish them both, but neither would admit to it. It doesn't happen often, but still enough to be really annoying. She claims that she does things and "doesn't remember" doing them. I have a hard time buying it, but guess it could be true with past drug use or a mental disorder . About a month ago she admitted to me that she had a problem with using oxy and that she was in debt. I agreed to loan her the money if she agreed to come clean and allow me to do random drug testing-which I have done and she is clean thus far. My husband also had a $300 pair of headphones that just dissapeared. Well this past weekend, my husband (who just had back surgery) had 2 percocet go missing and on the same day had $20 go missing. I am just fed up. Whenever we confront both girls it is the same thing "I didn't do it", "maybe he didn't know how much he had in his wallet". What can you do if you believe you know which child it is, but have no solid proof? I really do not believe that my 15 year old would do this, for many reasons. Please help. Any advice is appreciated.
