Hey S, ok, first of all, there was nothing you could do about your brother from work, so you probably should have just let h and mother handle it. Change the locks if you must.
Second, why is your h even telli ng you what your son said. And what is wrong with your son having to do some chores? I do not cook anymore either because my s either makes something for himself or gets something out- so your h needs to chill and tell s that if he has a problem with you, he is a young man and needs to talk to you about it. H should have said, please do not talk about your mother to me.
While I understand about you being upset that ow sees your son's myspace, you should not get involved. Try not to engage in verbal back and forth with your h. He is not hearing you and you are just spinning your wheels.
