Jenifer ...

First of all Jenifer is not cool, it's creepy ! -__-. Second Jim stayed with her because one nobody else would take her and two this 'girl' would give him the puppy eyes which made him feel bad. Also I believe Jim stays with her because Jim has no where to go at the time and he doesn't want his life to change. Jenifer stays with Jim because she is a monster and she doesn't know any better. Also these aren't relationships these are just poor men that get stuck with a monster they can't get rid of. They are together because she's just using him in order for her to get food. This 'girl' doesn't know right from wrong she's just concerned with getting food in her system and what is okay to her is a crime to society. I believe Jim also stays with her because of her body and he got very lonely after his family left him.
