wow, broken ribs? I'm thinking that is a little extreme; if you can't move, then that is affecting how you function on a day to day basis! What is the drive there that makes you want that? I personally like to play rough, but I would never hurt my partner, and would expect the same from them.
Some people lose their jobs over that kinda thing cuz it looks so bad-image doesn't sell! Makes the issue worse, for sure.

I think you should explore your thoughts and try and think about why you enjoy getting hurt, or maybe pain, I'm not sure what it is for you-do you know?. I'm definitly thinking not healthy! Try to figure out the specifics-what about it exactly do you like about it? Im wondering if you are recreating a scenerio from your past, so consider anything that happened to you as a kid too, ya know?

Why would a person not want to take care of themselves? I'm thinking you harm your body in other ways too, maybe even self savatoge? Take a look at your other habits-how do you treat yourself in general? If you come to find out that you don't take care of yourself, I would try to spend awhile in the "why" of it all. Seems to be causing you and another person relational problems-that's self destructive too, assuming the relationship you are in now is healthy. I donno;

Take care of yourself,
