Those guys they date are fucked in the head.  They have such terrible, terrible self esteem that they feel as if they have to date someone that literally needs them to survive and do everything for them. In the pigfuckers mind, they think, "She can't leave me. She needs me to bathe them and get them food... they literally cannot run away from me, I'm set.". The pigfuckers usually actually get upset when the fatties start losing weight, because now they don't need them anymore. They say that divorce happens quite a bit after weight loss surgery.  This is one fucked up world.
