I think that as a mother, YOU ABSOLUTELY have the right to look at everything he has in his phone or letters, especially due to him being an addict. I also think that being mothers, it is our duties to teach our boys how to be proper men. After all, a mothers relationship with her son is the very first female relationship a boy has, and should teach him the proper way to interact with women. Thats just my opinion..I hope it has helped.. Best of luck to you. Keep us posted!
