Here's this week's most outrageous relationship red flag story from the editors of The Little Black Blog of Big Red Flags.

The Story: My girlfriend and I'd been dating for about six months when she presented me with a Cartier catalog in which she'd circled various $40,000 engagement rings. She told me that these were the ones she'd be willing to accept when I proposed. We hadn't discussed marriage, in that we hadn't talked about getting married to each other, so this gesture came out of nowhere. When I remarked that I could go downtown and get her a nice ring for about 1/4 of the price (in theory), she replied that such a ring would not work. She wanted Cartier and she "deserved" to get what she wanted.
