H.S.
Ok...I understand completely what you are talking about. I am a divorced mother of one and my son lives with me but when he comes back from his dad's he acts up very badly. In my case, my ex and his wife have abused my son emotionally and verbally and border line physical. We have taken him to counselors where he can talk about the issues that bother him and to also get everything documented but there is nothing we can do legally because my ex and his wife don't leave any marks. My point to all of this is that one of my son's counselors told me that his acting up is his way of letting out his anger, etc. and that if he is acting out it is because he feels comfortable with my husband and I. Now in saying that, we don't let him get away with everything we just show a little more compassion with him and he straightens out in a day or two.
