Thanks for the replies so far....
In response to purple:- She isn't involved with him anymore other than being dependent on his money to support her and the kids. Yes she was naive getting involved with him in the first place, she beleived he would marry her. His wife is well aware of the afair, but he is now divorcing her (with 6 kids). Basically since I came along he decided he wants her (my g/f) back and is offering to marry her (after divorce) but she stopped loving him long ago and isn't interested.
In response to Terpe: Yes marriage is the goal, but I would hate for us to get married and only then discover that it is impossible for her to bring her kids to Uk! The stupid fact is the ex cannot look after the kids as he works and can hardly ask his wife to look after his illegitimate children! So if my g/f did come to Uk she would HAVE to bring them as there would be no one to look after them in Philly, yet from what I've read this would have no sway on the ECO.
