The use of hot water and soap does not belong to this protocols.
Invest in a healthy cookbook, you can try new dishes and find some that you like. Research plants that grow well in your climate and plant some fruits/veggies. Buy fresh ingredients. Make a list of healthy foods that you enjoy. Try cooking things different ways because anything can taste good if cooked nicely. (put oil in a pan and cook brussel sprouts until they are a little soft, season with salt and pepper.) Shop at Trader Joe's and Lucky's Market if possible. They have cheap and healthy products. I strongly recommend Lucky Market.
Well, for a healthy relationship, you should always have both of you trust and know that you can trust them, You should always be loyal to one another and want nothing but your specific other. Hope this gives you some insight :)
