Mother-in-law vent

So usually mil is great shes kinda the mother I've always wanted. some vent right lol but my hubby and I recently got a house. as a house warming gift she helped with furniture basically supplied the guest room with all the furniture I'm grateful. I get she didnt have to and i wasnt excepting her too but now seems like she thinks it's her room and not the guest room... she has stuff of hers from home on the wall excepting it to stay there( creepy faceless dolls) she buys things to put on the walls without asking and when I bought an ottoman for the foot of the bed she basically said why my room it doesnt go with anything...its grey and the walls are a dark blue grey...she picked these kitchen curtains ugly teal green bc of her comforter has veins of flowers bits it's so see thro theres no point for the curtains (windows are small) (kitchen size) but what she keeps doing tho is moving the ottoman away from the bed and leaving it there after here visits. I know this all sounds pretty and there are bigger problems in the world....its just my first home and my relationship with my own mother well shes basically crazy has her own drama so theres no relationship there and my mil and I are usually really good. It's just frustrating is all...
