Gosh, just had a look at this thread. Never took some of you guys for such "romantics". Love will conquer all.
I understand the OP. There are bells ringing, his spidey sense is tingling. A person (man or woman) who leaves a job as soon as there is an opening in another (an opening, not a fixed "this job has been already given to me" situation) is fluttering. Floating without fixed direction. Not facing reality. She may have a bucketload of money, but she's not willing to pull her part of the daily expenses of daily, normal life. So having money and not using it does not count.
To al of you accusing him of not loving her enough to withstand all the ups and downs and unexpected items that happen in a relationship, I remind you that a marriage/long term relationship is a team. Like a pair of oxen, you have to be pulling in the same direction at the same pace. It doens't matter who is stronger or bigger, but that they are in step. That is whay the "money talk" is vital.
Remember Autie Peng's advice: when poverty enters the room, love jumps off the window.(Spanish proverb).
Moreover, in a relationship, communication is vital, and to engage in communication, one has to open up. See, it is riskier now that he's contemplating bailout because she closed up. If she says "I want us to invest in selling ice to eskimos", fine, that is her point of view. he knows, he can supprt, concur, cheer her on the sidelines and not participate, whatever, he has a choice. But if he's going to support her without even knowing if that is her thinking -I've seen women who grow to resent it, blame the guy for not giving them the freedom to grow and other stuff because he's the provider so he's to blame- he has the right to ask a few questions.
I see some of the foreign guys just lay there financially in front of their wives like a troused chicken and I wonder, if the situation would be the same in their native lands. Would they be willing to concede that much? Don't tell me it's all for love because I believe there is a breakling point at that. On one hand, seems the woman is still a child , considers herself a child and hence expects to be supported as if by a parent -and we know how seeing your mate as a parent kills love faster than insecticide. On the other, there is an almost S&M quality to it, the dominated is actually the one holding al the power -when she takes the floor out of the guy's feet and you ar left wondering what happened. Seen both cases time and time again.
As usual, take this

with a pound of salt, being Friday, the darkest day of the week, and coming from Auntie Peng.
