Welcome to SR! Sorry you had to find us this way and I am glad you survived your attack. The person who stabbed you is not your husband. He is someone/thing else. Let the legal system have him. Be prepared, however, for letters from jail, declaring his true love for you, how he is better (maybe that he even found God), how he will never ever do drugs again, blah blah blah. They are all the same.
Take care of yourself and do what is right for YOU.
