Well, thanks for your replies. sorry I have been offline for a while. Here are some quick answers:
I value your replies and was not seeking to rebut them all - I hope all I was doing was providing more information.
I am meeting her in Thailand for personal reasons. My son is half Thai. He has not been there for a few years, and his last trip with his Mum was pretty horrible. As he is 15 I see it as our last chance to have a holiday there together. Mae will be very welcome and make it a complete and relaxing break. Plus it will be exciting for Mae to see another country.
When I sent the post I was having a little bit of doubt. I was amazed by some of the really negative responses, and pleased by some of your kind words.
As I said, I haven't got a lot to lose by meeting her in Thailand in 11 weeks time. I will let you all know how we get on. If it goes well I will visit her in the Philippines soon.
