It is easier than you think. Just pack up your stuff and leave. he is completely controlling you. And you are letting him. You want to leave. Go back and read your posts. If he is this controlling, it won't be long until he finds this forum and figures out your posting. then that will be the end of that.
Get your exit strategy and press.
if you don't, the next 20 years will just be a blurr. Take a read from those of us who stayed and hoped for better. It doesn't get better.
Good luck.
