I am a frustrated stepdad 
I will first provide a little background when I started dating my wife she her son was 7yrs old and she always slept with him or he would throw a fit this lasted until with her pleading and lack of sleep I interveened and corrected this problem every time this child wants something all he has to do is pout,cry kick and scream.this child gets everything he wants without lifting a finger doing chores The other day my stepson took my bicycle to his friends house without my permission 
and it was stolen. I told him that since he was respondsible for the bike he should pay me back 
this could be done by doing chores and getting paid for the chores wich he agreed too but never done.A week later he wanted 150$ shoes so he lied,cryed kicked and screamed until he recieved the money from his grandad for the shoes. I told him he must pay his debts first then he could do chores to save up for the shoes.His mother intervened gave him the money for the shoes.And she got upset at me for making him pay for my stolen bike.I am at my wits end ! I love my wife and step son but this spoiled behavior and disrespect he shows towards her. How can I prove to my wife that giving in always to our sons demands is doing more harm than good I can't live with a spoiled brat how can I handle this?
