Hi Hache,
When I met my wife, she was also tied into a marriage with a husband she was no longer living with.
The annullment is a very big challenge to overcome, it's time consuming and expensive. Your girlfriend will need to find the right lawyer, as many will say they can do it, but without experience could screw up the whole process. If the husband supports the annullment in any way, then you won't get it as that treated as collusion. Crazy process, but with the right lawyer and a decent amount of cash it can be achieved in less then 12 months, but is known to take upto 3 or 4 years. Ours took nearly 2 years, although thats on part because of naviety to not paying any special contributions to the judge's holiday fund.
Once the annullment is complete, it should be fairly straightforward if you keep all the evidence of regular contact, visiting the Philippines and the ongoing strength of your relationship.
You never know, you might decide that you want to live in the Philippines after a holiday!
