I have a problem that is the opposite of what these people are dealing with. 
 
My husband and I live with my coworker, and my son and girlfriend recently came to stay with us.  
 
My main problem is my roommate/coworker. She is a moocher, even though it's HER house we live in. I pay her as agreed, every month, on time, and she just takes advantage. We helped her buy a car, and she didn't even make a single payment before it was repossessed. She does not contribute to groceries and expects us to feed her on a daily basis. The utilities have been disconnected several times, and she has had notices about the mortgages not being paid on time. We have seen several instances of her money going to pay for things that are wasteful (clothes, shoes, eating out). I have always felt that it was not my business where someone else spends their money, but when I am paying for staying at a place and suddenly have no water/heat/lights/gas, it becomes my concern. I know what her income is every month and am convinced that she should have more than enough resources to have money for extras plus keep the lights on and contribute to groceries. I have made several attempts to talk to her *nicely* about putting her priorities in order, getting a budget and sticking to it, and going over with her things we are doing to make progress to get out of her house, but she is extremely defensive and accusatory.  
 
The problem goes beyond that. In short she is impossible to live with, but due to our own financial circumstances we are not quite in the position to move (we are about two months from having enough money saved up to rent a place of our own). She is unable to communicate...she walks around throwing a tantrum and refuses to talk to us and tell us what is bothering her. It seems that she expects us to read her mind. At work I often have to listen to her complain often and loudly to *no one* in particular about how bad her life sucks and how she should just go kill herself. And actually, when she's not letting her attitude get the better of her, she is a really cool person to be around. But I don' t know how much more I can take! I am currently working two full time jobs in attempts to get out of the situation faster (which is nice because it's less time at home having to deal with a volatile person). It's very frustrating. We do appreciate the fact that she has given us a roof over our heads when it was much needed, but it's causing a severe amount of stress. My son and his girlfriend are searching for work but they are young and it takes time to find a job. Finding another place to live is not very easy because our credit is bad because we've been through a series of unfortunate events (some our fault, others not). Landlords either don't want to bother with us or want such a high amount to allow us to move in that we'll never afford it. Short of constantly wearing ear plugs so I can tune her out, I don't know what else to do to deal with someone this difficult. 
 
We have taken alot of advice about finances to heart and are following a budget, getting things caught up, and feel we are doing everything we can on our end.
