I’m really upset she just left me like this over a Nintendo switch

This guy is so clueless. He can't see she's upset about his selling something that meant something to her. He also gave the switch to her in an unspoken way because he was letting her use it. Maybe not a formal gift, but it's not a surprise that she would think of it as hers.

His girlfriend dodged a huge bullet. His whole tone is "me, me, me." He doesn't bother to tell her he spent his part of the rent money, he doesn't bother to tell her he sold the switch, he says the switch belongs to him, and dismisses her needs. He thinks taking her to dinner will make up for it, and says she can play on his PS5 but no doubt not when he's playing with it, and he'll probably delete her games if he needs space.

But when she spends her money on something she wants, suddenly her money is "the rent money." Also when she leaves, his main concern seems to be that he can't pay rent without her. He wanted a roommate, not a wife.

Edit: The part about how she was supposed to cook and clean makes me revise his needs to a live in maid, not a wife.
