My XH would not allow me to have a gun, said that I would shoot him some night and tell the police that I thought it was an intruder. Lol !
When I had him removed from our home, I applied for concealed carry. I have always been a target shooter, love bow and arrow, glass shot, etc.
Learn safety first and how to shoot. Then situational shooting. It saves lives.
Having a measure of control over our lives, will bring so much strength to you.
I lived in fear that he or someone he knows would follow thru with the threats to have me cut into little pieces and thrown in the lake. Said no one would ever find me.
Follow through with your plans and set up other venues to help you in any event. Pepper spray, baseball bat, neck knife (designed for women), stun knuckles (if legal in your state), anything you can do place these between you and the perpetrator.
