I practically raised my nephew his entire life. We were very close and I took a lot of pride and felt responsible for him. The past couple of years he stopped being involved in family functions and stopped coming around my house. His parents (my sister and her ex) don't ever expect much of him and don't encourage him to do right rather than wrong. Recently it has been found out he has been smoking marijuana consistently and was caught with weed on his person by a police officer. Even through all the trouble he is causing for himself and his parents they are not making him stop the marijuana use. They are enabling it and ignoring it. I tried to intervene and I tried to offer assistance but my nephew has resisted me and and has become very hard to even talk to. He's a know it all and has smart remarks for all the help I have tried to give him. Long story short I have sort of washed my hands of the entire situation and I am trying to find peace with it all. I feel like he is my own child and to give up on him feels like failure but because I am not his mother he doesn't think he has to listen to anything I say. I have my own (small) children to care for and I cannot stand the disrespect or drama that my nephew brings to the table. I'm just looking for reassurance to my choice. Do I let go and let God or do I keep trying to intervene?
