Cont...My boyfriend and son not getting along?

I think ur absolutly right I think the problem lies in our son not having enough dicipline, i've been doing time out for about a yr and it still doesnt seem to be working, i'm the 1st to admit that I have an out of control 7yr old and I need help, my family is falling apart and im pretty sure its my fault, its crazy how a complete stranger answering 1 Q can make u realize something u couldnt see b4 .if u have any suggestions on how to dicipline i'm all ears, thank you.
