hmm..the mother in-laws. My wife said her mother wanted to come an live with us in England when she eventually move here but even before reading this I know that is recipe for dissaster so have a cunning plan to make sure this doesn't hapen. Not even a visit, Just can't risk it.
Also, the timing of her bad behaviour towards you is a suspect. Has she already have her ILR? how come your snoring or whatever never bother her before in early stages of dating. Is it bcoz she is holding out until she gets ILR?
To weed out filipinos only after Brits to use for ILR? I have always advised Brits in early stage of relationship to make it clear to the filipino gfriends that you are the one who will move to live with her in the phils.(Ofcourse this is not true but this might reveal her true colours)
If you say you're the one who will move to her to start family in phils, within a few weeks/months the ones who are only after ILR will regard you as waste of space and dissappear to find another man. But if she still stays with you weeks/months after making it clear that you're the one to move to live with her in phils then clearly she is not after ILR and only after proper relationship. If you get this right at the begining, then you will save yourself a lot of headache later.
Make no mistake about it there are lots of filipinos out there willing to take advantage of us westerner foreigners for ILR and way out of phils and they will go to any lenghts including marry and yes have kids to conceal their true intentions. It's up to us find a way to figure them out and weed them out at the earliest opportunity in the relationship.
