How to save yourself from getting harassed living in the same house with harasser?

I am studying , haven't gone to university yet. I hope once I am graduated I'll be financially independent. For at least 6 months I m stuck here. I live with a person who harasses me a lot but in the end I m blamed that it's my fault I act in a certain way to seduce them I have been serverly harassed 6 times during last 3 months. How to save myself for these 6 months?
