I am having a horrible time with my wife ( the mother of my 3 kids) she is lazy, a liar and steals prescription medication from my son who needs it desperately. She goes off the deep end and yells, screams, and says horrible things while the kids are standing right there. She really isnt a bad person but i know if i finally get smart and leave she will try her best to take my kids away. Now for the past year i have been a stay at home dad and turned the kids around completely, When she was home the kids were stunted in all aspects of life. How can i end this nicely or how do i take legal action?
