A couple of years back we had this problem and my partner was not even in the UK, we had constant pressure to solve every problem that came along and often my partner Ana could not talk to me about it, this creates a very poisonous situation between a couple.
It really is not easy, in our case I know there is genuine desparate need in our family and I have helped as much as I can but we cannot possibly solve all their problems alone, we have two kids of our own to support :( and times are getting bad in the UK, we have to think of our future and our kids future!
Having them dip into the foreign bank every month or so is doing them no favours!
