I think that's a common theme. The abuser doesn't just break the body, they break the will. It will drain the life from anyone.
I had someone say he's had women make him mad enough to hit them but he didn't. Maybe it's because I've never been in a real relationship I never felt that way. I'd like to say I wouldn't hit her but I haven't been in the situation. I believe I have the strength to not do it. I've seen the aftermath too often.
My dad had a ramp built when his condition got so bad that he couldn’t climb the three steps to get inside. He was lucky in that a close relative is a carpenter who built it for just the material cost. But yeah, I think you should go for. Being able to go outside did good for dad’s mind at that point.
