I'm apologizing ahead of time for this long post. I and my husband had one child prior to us meeting each other and now we have one together with one on the way. My step son lives with us full time because his mom was having a difficult time with him and also my husband wanted to be more of an active parent in his life. In the beginning things were okay. I did notice how his son had behavior problems and was not doing well academically. My husband would get calls from his son's old school about his behavior often and to sum it all up he ended up having to go to summer school. Since being married we are now under the same roof and things have gotten worse. My step son will not listen to his dad and anytime he tries to tell him to do something he starts yelling, slamming doors, throwing things around, crying and just being full on disrespectful. My step son does not act this way with me so I have acted as the mediator to get him to call down. I was okay with it at first, but now since he came back from visiting his mom over the winter break it has gotten worse. I am currently four months pregnant, my oldest is nine and then our son we have together will be turning one in February.

I feel so guilty especially after talking to my daughter about how she feels. She just recently had a birthday and was saying she hopes her step brother doesn't go into his behaviors on her birthday and unfortunately it happened. His mom said she has no problems out of him, but from what has been said by my husband and in a way his son he is allowed to do whatever he wants. I and my husband have both started therapy to figure out why things are the way that they are and why we have been arguing so much lately. When I think about it all of our arguments have to do with the way his son is behaving and how much it is making an impact on our household. He is currently failing all of his classes at a new school, but his behavior there is okay. His mom has said that she wanted him to come back at the end of this school year. I love children and have worked with them for years, but I am exhausted coming home and dealing with how his son acts. I don't know what to do anymore.
