Cohabit (Who at a disadvantage)

hi boy ,facing with such a thorny problem,maybe you felt a bit annoyed.we have the authority to choose the way of life.but i won't choose cohabit,because when people seperate with each other,generally they won't be friends.They were hurted,both of them.For men,their broken hearts manbe the main problem.It will be more serious for women in china ,you know ,men always mind their wives first time,so it's more difficult for them to marry a husband,have a happy family and so on.Chinese is traditional,we just follow it,that's ok.
