KG - there is conflict avoidant during an R (unhealthy) and conflict avoidant during separation (saving yourself grief). I get the sense you were both. Some might say you need to kick WW out of the mbr and dismiss all types of affection. I personally think it's okay to play the conflict avoidant part right now as long as it is temporary and all the while you are still moving towards the D. There is only so much we can handle during the highly stressful and if simply not fighting is your goal that's a worthwhile goal. I also do think it could end up better for you to not fight her on legal stuff later.
That being said, if you don't want it, reject it. I think the "not fighting" approach only works if you're truly ambivalent and just can't muster the strength to be bothered. If you find it's sapping your energy even MORE to accept her cuddling then you should stop it. What if you closed the bedroom door while sleeping? Is there a lock on it? That would give her the answer while you get to remain silent.
Don't worry about feeling hot right now but know it will come back. Accept that as truth. Later, when you are truly separated you can consider some cute lingerie/undergarments in a style you feel great in. Being hot for no one but yourself is a great way to feel confident in your every day life. I got all matching undergarments after my separation so that no matter what day of the week it is I don't have to give it a second thought - I always match under my clothes and it always looks cute. No one knows this but me. Those bras or underwear you only wear on laundry day and they live in the back of your drawer? GET RID of them. It's kind of a great feeling to know everything you own is new and something you like.
So WW is cleaning out the apartment. What's the countdown for her moving out? I'm hoping it's soon?
