While I agree with Mike that one would do anything to get out and it would be a reasonable effort on the part of the young woman, I'd also note that right now you might well be the thing she must do to get out. That doesn't mean you will be the thing she has to do to stay out once she is out.
If I were you I'd be very careful.
I'm sure she is exactly who she says she is, and a wonderful human being now, but, quite frankly, she has exhibited a willingness in the past to use a man to alleviate her and her family's suffering. I hold no judgment against her, but I would not want to be the next man she used for that purpose. It is very easy for a man from a developed country to overlook the motivations of a woman from a developing country. I've spent a fair amount of time in developing countries and have received my fair share of attention from young women in them. I always keep in mind what I, as a 43-year-old man who is in typical 43-year-old shape has to offer a young, beautiful woman. With that in mind, I keep my wits about me and treat these young women with care and respect.
Have you been to the Philippines to meet her?
Have you lived in the Philippines for an extended period of time to court her?
Your profile says you're from the UK, are you aware that the UK has quite stringent laws regarding bringing in a foreign spouse?
I mean no disrespect. I hope you will take this post in the spirit in which it is offered.
