Should I take my mom and entire family in with me?
i would take her, she took you all your life, you can always get help fronn social services if you need to
You're her ticket out of a toxic life. You can volunteer to help her out but make sure she knows your situation financially before deciding anything. You need to help out your mom anyway you can.
No. Mom needs to take responsibility for herself and her decisions. As a responsible adult she should have made a plan before choosing to leave your father. Its not fair for her to make her problems yours when you had no say in her decisions. And that is aside from the fact that doing so will likely put your own tenancy at risk.
Tell her to get a lawyer, now. If she's got kids with her the courts will make sure they have housing and money from your dad while spousal and child support issues are worked out.
look i know they're your family but it's not up to you. you got your own life i'm sure,she has no one else who can help? there's gov programs she can get for help. maybe she needs to look in to that and have something worked out before she ups and leaves.
