Myy boyfriend(25M) and me(24F)and my Family

So here is the story.Anyone do reply When I walk around the house or do some household work my body including my private parts are touched by my father my brother and when I bend my breast was fully visible and I use to sleep with them my brothers at the same bed my even after age 10 and once in a video my 10 year old brother spanked me in the ass also took my bra out infront of my brother change infront of them.And when I bath the window above my washroom is open and can be seen from above where many people live.And I use to change in a room with no door only curtain and window transparent.When I was bathing once I saw my brother peeping through the washroom My father my brother everyone touch my private parts whenever they get a chance whether I am doing some household chores or simply standing they don't ask me to move or they don't do the same instead they brush against me and touch my private parts sometimes with hand and sometimes with their private parts.Like they just brush themselves against me which leads to them touching my private parts one day when I bend to take something out of the fridge my brother went behind me and touch my butt with his private part so what should I do.He once tied my leg with belt and started spanking me in the butt when he was 11 or 12 i dont know.Once my brother was peeping through my bathroom door while I was bathing and when I changed clothes before I don't use to close my door or window and I also took my bra infront of my brothers or change somethimes infront of them or they come in when I use to change my clothes.And also when I use to sleep at day they come and sleep in my bed like weird.My boyfriend knew all this and he said to leave the home immediately but I couldn't so he told me to change my routine like bath or sleep when they are not at home and do change with nicely closing doors or windows.But i didn't so he broke up with me but my parents are looking for a marriage proposal.Please read my previous post for it.
