My girlfriend always blames me for what she does for me and it's making me tired.

Every time my girlfriend and I have an argument, she ends up pointing out everything she “does for me.” What if he sends me money, what if he stays up late with me, what if he does things he doesn't like just to please me. He even reminds me that he bought Minecraft to play with me... and then he reproaches me for it as if it were a debt.

The truth is, it bothers me. I know if this is normal or if I'm exaggerating, but it already feels heavy.
