Ady 5k is a huuuuuge amount to the avg phill. Put it one way My Wife sends about 30 k plus her mum sends a smaller amount of money back home as she also works abroad. The quite a few kids are being put though school and uni (very nice ones at that), houses are being improved along with the running costs of an avg extended family being met.
I take it you have never been to phill ( hope that doesn't sound rude Ady) as you would reailse a working person would be very happy of a 5k subsidy trust me.
Like others say don't contact her for a few days or a not as much and see if she makes an effort. Thats nothing about the relationship being brit/phill just a good idea to make sure both parties feel the same.
