my friend here is what you can do....
> if your back home in manila... collect the evidence that your husband/wife is having an affair. a solid evidence.
> if you have it, go straight to NBI.
> the NBI will ask for help from the INTERPOL.
> INTERPOL will definitely give a hand to your case and will contact the local authority here in doha.
> BUT... make it sure you have a SOLID evidence.
> OTHERWISE forget it....

just pray and let the lord handle the case....

good luck
