Advice
I can give you advice......
I was in an abusive relationship for 18 years. He drank a lot and when the alcohol was flowing, his "courage" became stronger. I was also his punching bag, both physical and mental. I am a strong believer that the mental scars are far worse than physical. Physical you can see....mental you can't.
I never believed that I was part of the problem until I came face to face with that fact. Once I realized I was the enabler for and to him, then I began to take steps to correct it. I divorced him many years ago.....where I got the courage I may never know. But, it was the smartest thing I ever did. He continued his cycle and then committed suicide in 2001.
He was never in Vietnam, but I have known many who served in that war and it affected everyone I knew.
My advice.........GET OUT OF THE RELATIONSHIP and don't look back. DO NOT TAKE HIM BACK. HE is destroying your physical, as well as mental health. Seek counseling for yourself like I did and find out all the "why and why nots" of what makes YOU tick. You are worth it.
