The thing is, most men only think with their private parts when
dealing with the opposite sex, not their brains. Seriously, ask
urself if u are in this relationship because of sex, or because u
want 2 live with this woman forever. If it is because of sex, then
leave her. If u wan 2 live with this woman forever, and she loves u
as much, then quickly go get married. There are many reasons why a
period can be late, such as work stress. If she is still worried,
ask her go see doctor or buy a pregreancy kit to test. If she is
pregreant, then be responsible.
