Hi!
I just wanted to chime in with the others that a vegan life isn't a guarantee of weight loss. I've been vegetarian since I was a teenager. My diet is pretty close to vegan because I very very rarely have eggs or milk products... but ice cream is my one non-vegan weak point.

I've had times in my life when I was technically vegan. Most of my time i've been obese. I was obese as a teenager before going nearly vegan, and obese afterwards (for the most part).
Now a raw diet is even more extreme than simply going vegan. I'm certain there are health benefits, but it sounds like such a diet isn't realistic for you as a "lifestyle change". I think you gotta be pretty committed to the bit if you want sustained weight loss from a raw diet. And i can promise you that weight loss is NOT inevitable even with a raw diet. There are plenty of high-calorie/fat raw foods that can get you in trouble quickly.
Plus... weight isn't all about diet. For many people, it just isn't that simple. You could have a very slow metabolism or any number of medical conditions that would make weight loss difficult. From what i can understand, for some people certain types of WLS (like RNY or DS) are the only way to fight against their body's natural tendency to stay obese. I'm not a doctor, but just learning a lot from reading about the experiences of others and the opinions of medical professionals.
I guess I am saying all of this to say that the raw vegan diet isn't the 'perfect solution' for everyone (or even most people). It's hard to maintain for a variety of reasons, and it isn't a magic bullet sort of diet.
I hear ya about not having a husband totally of board. It sounds like he isn't quite with you 100% on either the raw food diet or the WLS. I think his support is key - whatever form that support may take. It'd be wonderful to have other family on board - but I'd worry most about your husband since you obviously live with him and interact with him more than anyone. If you had his support, it could make it easier to deal with the criticisms of others.
Would your husband be willing to read some information on the surgery? I know I have a HARD time getting my husband to read anything, though. LOL Maybe he'd be willing to attend a seminar? Or...are there any pro-WLS tv shows that might get him on board (at least to see that it isn't an "easy way") I don't know what these resources may be... but it sounds like he has a lot of preconceived ideas about WLS and maybe if he did some research he would better understand it and be able to offer you better support. Maybe someone here can point out some WLS resources that would be support person/husband friendly.
Ok... I've typed a lot of words. Mostly i just wanted to give you this:
