Family Issues Support Group
Family issues is a huge range that go from minor conflict to major misbehaviour and even abuse on the part of individual members of the family occur. Whether you feel you are in a dysfunctional family or you're dealing with a very specific issue, this is the place to talk about it and find others who might be going through the same thing.
First, yes, you have every right to demand that this GROWN MAN (your step-son) clean up after himself.
Second, your husband is obviously not exactly a great guy. He might have the potential to be, but he certainly isn't now. Him talking to you like that is unacceptable.
If I were you I'd take time to sit down with your husband, calmly explain that you feel like you're being disrespected, and if he reacts so abrasively again---you might need to start rethinking your marriage.
Good luck! I've been in many rocky relationships and have always learned the hard way. You don't want to be looking at your life ten years down the road and thinking about tons of red flags that you SHOULD have paid more attention to. Don't let loving your husband blind you from what's acceptable and unacceptable.
