The daddy needs to understand whatever the problem is it's not working well for you. You shouldn't get married until this problem is addressed and you can combine families successfully. Thats what you owe yourself but first the children. How old is the stepchild? If he is the nine year old i was in a very similar situation. I think if you focus on more positive and less negative you can start to direct the family to get along more. Its hard work being blended. Just ignore the little things like the candy. Maybe you start something fun and exciting that daddy doesnt do. The kids know that they are getting under your skin even if you think they don't. Just do more things with the kids whether it be during dinner time getting it ready. Takes time to earn respect and understanding from the kids. I cant remember what the suggested ratio is but every time you get on to the kids its negative. How many times have you made positive contact? It could be rough even if you bring it on yourself to always be in trouble and being griped about and compared to with better kids? Try 10 to 1. Make sure for every 1 negative you give him 10 positive contacts. It makes it hard work being a parent.
