If I were you I would confront her and tell her everything I think about her. Then (provided the bed is mine) I'd forbid her to be on it. If it's not mine, I'd buy my own bed and set it up in the lounge room. She can find her own way of dealing with it. There's no way I would just suck it up and put up with it until May.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
