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.

Next fight...leave. He's not worth going to jail over, and neither are Wendy's fries. Walk away, leave, sleep in your car if you have to. If you don't have a car, make an exit plan for where you'd go and what you'd do.
If you can, find another place to live.
If the police come to talk to you, don't talk. It's one of two situations, one they're going to arrest you...in which case, you have the right to have a lawyer there. Or two, they're not going to arrest you...in which case you have the right to leave.
Nothing you EVER say to the police can help you. EVER.
Yes, and next time, don't be around the drama.
