Money will sure be an end to my relationship.. oh and his arrogance.

I can't work due to personal issues, my fiance is working. He gets paid fortnightly, he wants to spend $1000 on a toy that he wants. that leaves us with $200 for fortnight, not including petrol, food and whatever else has to be done, I like to have money there for an emergency. I don't want to live paycheck to pay check. He always says that he works, and he knows that I cannot work. I feel like crap. I don't want to be with someone who throws it in my face. He will sook if I say that's a ridiculous amount of money by sook I mean, not talk to me, tell me it's his money, separates us as a couple. He also buys games every fortnight too. Every fortnight this situation happens. He always says that we are a couple so it's 'OURS' but every fortnight he says it's HIS. Hmm I need advice please ladies.
