My husband wants to starts having a Domestic Discipline Marriage....?

My husband and I have been married for 7 years and have a great relationship 90% of the time. He is a very loving, protective man who would do anything for me. He treats me better than anyone has ever treated me. There are times though when we fight and a small argument will turn into a heated battle with me screaming and threatening to leave (even though I would never leave him) and storming away slamming doors. I can get very mad very quick and I often say things that are hurtful because I do not think before I speak. My husband jokingly calls me a "guinea brat" because I have never had any kind of authority in my life so I am used to doing what I want, how I want and when I want, I didn't have a dad growing up and my mom worked 3 jobs to support me so I pretty much was on my own and had no one to answer to and in turn I became very tough and growing up in nyc I was very street smart. I had become very promiscuous by age 14 and got involved with drugs by 15. For the past 4 years I have been struggling with an addiction to pain killers. My husband found out and insisted I get help and stop. I did, but I still slip up sometimes behind his back. I don't always tell my husband the "whole" truth and will often hide things from him because I know he will get mad at me and I don't want the fight. Well recently my husband brought up the topic of a domestic discipline marriage. I did some research on it and I can see why my husband would like it. I wouldn't be "allowed" to talk back to him or call him nasty names or "misbehave" and if I did then he would have the right to "punish" me. I told him I would be willing to give this a try because I could stand to learn some respect and think before I shoot my mouth off. My question is, are there any other wives who practice this type of marriage and if so, how do you change who you are after 29 years? I am old fashioned in some ways such as, I believe the husband is the head of the household and has the final say when it comes to decisions and I do have dinner ready for him when he comes home. cleaning the house is my job and he goes to work. I try not to spend money without checking with him first but I do these things not because I'm afraid of being "punished" but because I love and respect him and want to make him happy. My husband said that because I never had any kind of discipline growing up that it would benefit me to have some now. My reply initially was I've gone 29 years without a father and I sure as hell don't need one now, but maybe he's right. Maybe it would make our marriage stronger because there will be clear lines drawn and consequences will be known. I will think before I shoot my mouth off to my husband from now on and I will respect him more. Any advice from women who live this type of marriage or input from anyone who has any advice on how I can change myself and if this is even the right thing to do or should I tell him I'm not doing this and continue to be a "guinea brat"? lol thanks everyone!!
