I HATE MEN

i hate it wen men ask women for money, but off late my bf keeps asking me for money… and he doesn’t even ask politely, he just demands for it as though it is rightfully his or something… I’ve told him no many times previously, but he just doesn’t stop asking for it… i cannot support anyone financially n he shouldn’t be asking me for money because i feel bad everytime i say no… how do i tell him politely to stop this…
