para sakin, i think it's okay mag-live in if you really have plans of getting married to that person. it will be an advantage kasi you'll get to know each other more. and sa set-up na ito, you should think na talagang husband-and-wife na kayo. kasi pag hindi, dun nagkakaproblem eh. i think tama si sis mooncake and leaves, un legalities lang ang kulang sa ganitong set-up and that shouldn't serve as an escape pag ayaw nyo na. i remember when my hubby and i decided to enter this kind of set-up a year before we got married. he told me, no return, no exchange. hahaha:D funny, pero my meaning na talaga na parang wala ng atrasan. and if there would be problems, you should work things out like husbands and wives do. goodluck sis, i hope that you'd end up marrying this guy din later.
