Cut tour ties with fats. They are impeding on your lifestyle even if you don't realize it. From putting forth the extra effort not to be offensive or taking a photo so it hides as much fatness as possible, your life is being limited and energy wasted on maintaining ettiquette for someone who has no self-control or self morality. They are taking away from your life in ways that you would not tolerate from a skinny person. Any non-fat can contribute more to a relationship than a fat person.
