Liek woodpam says, career is definately a factor in this debate (as well as kids, which I'm assuming you don't have, as you only mention shopping and cleaning), but as you don't mention it, its hard to see what other options are available to your girlfriend - in other words, if she's not working or pursuing something then she has a lot of time on her hands. How about you doing the shopping and cleaning as often as you can, and she can't complain that you're doing it, and then you're freeing up more time for her to do whatever. Also, just wanted to say fair play to you for seeing things the way you do with this problem you have as some blokes would sit back and say 'thats fine with me, love' (I'm not saying ALL blokes, just some, I'm not trying to start a gender debate) :)
