I'm from the Philippines and I need help regarding the marriage rules in Jeddah Saudi Arabia. My went to work in Jeddah last May 26, 2014, not knowing that her ex - bf is in Jeddah too. After 3 days I've learned that my gf reconciled with her ex before she left here. Literally cheating on me before she left. We have a 9 year old daughter, we're okay when she left Philippines. I have a hunch that she and her bf in jeddah will going to get married there. Is there any possible way that I can object or say request for the consulate to deny their marriage? HELP!!!
