Wow! What a sad story. I never been in an abusive situation but have plenty of friends who have. I don't pretend to understand why they stay, except for extremely low self esteem. What I can say to this lady and others in similar situations, if you can't leave for yourself, leave for your children. What's happening in your home is poison to your kids and ruinous to their future. Do you want your sons to grow up believing this is how to keep a woman? Do you want your daughters to live through this hell? By staying, you are setting the stage for this exact situation to happen to your kids. You are teaching them that all this nonsense is normal. You are destroying their chances for peace and happiness. They deserve better!
Look into your children's eyes and SEE their fear, LEAVE FOR THAT. GO TO A SHELTER IMMEDIATELY.
And, please start teaching your daughters how to stand on their own two feet and make their own money - - knowledge is power! No one can hold you hostage when you know and BELIEVE that you can make it on your own. Weak men seek out weak women. Abusive men seek women they know they can control.
I've met men who have tried to overpower and manipulate me, and I don't make excuses for them ("he's just having a bad day"). I simply say, "this is not how I'm use to being treated and you do not need to call me anymore. I'm not the one!" and you know what, they don't call anymore because I'm not the type of woman they want. They know right up front that they cannot and will not walk a dog on my back. My point is, you get a sense of a person at the beginning of a relationship - - don't accept bullshit in the beginning and you won't get bullshit in the end. You might not wind up with that man, but who wants and idiot, and/or a black eye?
LOOK AT THE FEAR IN YOUR CHILDREN'S EYES AND LEAVE FOR THEM! DON'T RUIN YOUR KIDS CHANCE FOR PEACE AND HAPPINESS BY STAYING WITH A FOOL. I UNDERSTAND THAT IF SOMEONE IS THREATENING YOUR LIFE, THAT YOU ARE AFRAID, BUT ISN'T HE, OR HASN'T HE ALREADY KILLED YOUR SPIRIT, YOUR SOUL? SEEK HELP AT A BATTERED WOMENS SHELTER, GET A RESTRAINING ORDER AND GET YOUR OWN GUN!
