Am I asking for too much?

Basically my girlfriend (lesbian couple FYI 💕)she works from 9am-6pm every day except weekends. I am basically a stay at home housewife I clean, cook, wash clothes, iron clothes, feed the animals, wash dishes, dry dishes etc you get the point and all's I ask is like sex once a week but she says she's too tired. I respect that she's tired but she gets a whole weekend off and comes home and plays on the Xbox for hours but then says she can't be bothered to have sex.. or does other stuff when we could be having sex. - like, a woman has needs right? I'm not pushy or anything I just tell her that I don't want to have to ask for her to show me a little affection.. she never even cuddles or kisses me unless I ask and if I ask her if she still attracted to
