My girlfriend just confessed that she will not be paying my rent for me anymore

It’s already hard enough for me because I lost my job and I can’t sit at home all day playing Xbox. She tells me I need to find a job and that I’m a grown man and need to act like it. This is not fair for me because I live with my grandmother and she cooks for me and does my laundry for me and folds it nice and neatly into my dresser. She is very helpful unlike my girlfriend who just nags me constantly to get a job. So what if I’m 35 years old and have no job ? My grandmother charges me $400 a month to live here. Who in their right mind would want to move out if they were in my place ? Nobody ! My girlfriend needs to help me with rent till I find a job. I refuse to be treated less than what I’m worth. My grandmother says I’m a king so I expect to be treated like one.
