i did this gayuma thing to my ex bf of 6yrs,it worked but there is this rule in gayuma that you cannot tell your bf na pinagayuma mo siya otherwise magkakahiwalay kayo or some sort,i told my ex i did it to him and voila after a month wala na kami for good..i dont know kung maniniwala ako but my relationship with my ex is horrible so,its really not worth it,nung ginawa ko yung gayuma on going 3yrs yung relationship namin,nagtagal kami ng 6 horrible years lols
