What would you do if your girlfriend started acting differently when you lost your job?

Let's say that you've always been employed but then you lost your job. At first she says she'll always be by your side but after a week she goes out to eat and only cooks for herself. She says it's because she only has money for herself but unfortunately you notice she's become more distant. She's not mean but you do notice the distance/ being less interested in you ever since you lost your job- what would you do?
