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.
Although you may have not witnessed this last event you have witnessed prior events if I'm understanding this correctly. Someone has to be in the wrong here.
DH shouldn't make threats and daughter unless she has medical issues that keeps her home bound is old enough to be living out on her own.
I say take a step back and analysis who is really the one being controlled in this situation...
i've told them that they can complain to me about the other, and i'll listen, but i am not going to say anything in support of either of them, especially since they both twist what i say or misinterpret (told them that too). i also told them to stop putting me in the middle - their fights are THEIR problem, don't make it mine! and until they do something proactive about THEIR problem, like going to therapy, i have zero sympathy for either of them, because it takes two to tango.
Don't waste time tryin go smooth things over that is up to them. It can be as simple as u want it or u can make it more complicated by letting their problems upset ya. Find what works best for u.
