Agreed--leave her alone. I've lived with people in early sobriety, and it's no picnic. I was glad, when I got sober, I lived by myself--I would NOT have been pleasant company.
Just be pleasant to her, but you also don't have to accept actual rudeness or hostility. But just wanting to have space is neither.
And again, focusing on your OWN issues. You sound a bit on the needy side--which might or might not be a product of living with active alcoholism--but it's not really conducive to a healthy relationship or life.
