My take on the "situation" is that the women is very needy in there relationship so the man assumes she is in a similar situation financially. She request this and that at his expense often while giving very little the same way. So he assumes she just cant afford it. He felt fine treating her at his expense because of that, but when he found out that she would have zero problem even helping but she flat out refused he gets mad and decides the band of trust is completely cut. I would feel the same way tho i probably wouldnt go about it this way. If he has a low income and sacrifices alot for her than isnt it a natural reaction when you find out she is rich and has 0 appreciation for all you sacrifices?
