he can do better than me.. wow that really hurt!

My partner and I just got a house (rental) so you can imagine the stress when we both don't work, we live off new start payments which is $400 a fortnight. That's TOUGH! anyway, he wants to buy a game that's worth $66. I would be fine with it but the fact that he had brought a game on Sunday for $100 and he just spends money here and there. I don't spend anything. I mean we can't even afford food. I said no we need this money for rent. anyway he gets angry with me, I don't seem to care. but I am so sick of getting called a useless cunt. A GIRL CAN ONLY TAKE SO MUCH RIGHT?! He gets really nasty and tells me to fuck off, that's his money, Kicks me out of our house. then he feels bad so he tries to kiss me. I'm not having any of it. So I tell him I don't want to be with him anymore. I am so hurt. and he tells me ' well I don't care I can do 10X better than you." my heart is fucking broken.
