To my understanding she has decent career, and a guy and with same standard if both willing to work they could have more then decent lifestyle.
The issue come when she want him to solely responsible for her lifestyle, (she is not very lavish but still a good one), it seems to be a bit unfair to me.
If the guy is educated and employed, I'm sure she will be fine if she doesn't work. She just needs to commmunicate this with her future husband, so there are no miscommunications. I'm sure you guys will be able to see which type of man could suffice her way of living.
