There's an intriguing woman I've been seeing who I am considering for LTR. I've been spinning plates for a while and I've gotten along with her more than most. I found out pretty recently that she also happens to be very wealthy (family owns large manufacturing business, though she works in another professional field). The strange thing is though, she is rather stingy -- for example, in the summer she minimizes use of AC in her apartment, doesn't like to spend a lot of money, takes economy buses instead of planes, trains or cars on interstate travel, and in general is pretty frugal. Is this a red flag or a virtue?
