I was not married with a child but I have been in such a similar situation its crazy to read your posts I eventually was walking behind her and thought how great it would feel to choke the life out of her so I did what you can not as easily do I woke up the next morning and left with the clothes on my back and my dog and never contacted her again I feel for you the constant following around and not a moment of peace is by far the worst just keep hoping she does not kick you out call the police and lie and like a fool I still went back after all the DV shnit was done and she continued to pull the I'll call the police card then one night I thought I'll give you a reason to call I did not and ran the next day when she is trying to push your buttons it may be really hard to do but kill her with kindness it may get you some space because they too want left alone though it may backfire and infuriate her if she knows that is what you are doing
