I love my kitties sleeping in my bed even if my partner and I are left to fight it out for one small half of the bed! I suggest that, instead of kicking her out entirely, move her to the end of the bed or even a basket or a comfy bed right next to you on the floor. Most cats will sleep almost anywhere (linen closets, on top of modems, etc) so the desire to sleep in your bed is a desire to be near you!
