Aunt's fiance

Question... okay so last night I dropped a jenga block and went to pick it up and then my aunts fiance said what a view... and then said I get the bottom end... totes inappropriate. His been very innaproptiate lately and my aunt is leaving for the UK on the 15 of Feb so I will be staying alone with him till the 1st of April because then we also moving to the UK.... so slightly worries he might pull something. I was also in her Last night and then he knock on my door while I'm in bed to show me a video camera he found and comes right up to my bed to show me it can film in the dark....... so yah his been quite innaproptiate lately. Looking at my butt.... or the other day I was leaning on our washing machine and my butt pushed the on button on by mistake so i said what was that and to push me off the washing machine he grabbed my bum to do it and said it's your big bum...
