Girlfriend's ex won't go away.
I've been together with my girlfriend for almost 3 years now. She has a house which she rents out two rooms (her ex and someone else). The ex has been living there for a year. The ex doesn't have a job (not able to hold a job for more than a month) and isn't looking for one and hasn't paid rent for months. My girlfriend's always comes home from work tried and stressed out. I'm 100 miles away 3 days of the week for work. We're trying really hard to pay the bills. Lately I have been getting arguments with her about her ex. She says she doesn't have any feelings for him. I just don't know what to do.
