Cry me a river.
I find it disgusting that the writer would describe the guy's situation as being "sucked into a trap" (implying Japanese women are just scheming to catch a man) or that she would be sympathetic to him for being dumped by a girlfriend who wanted a stable breadwinner for a husband. The writer already states that "many women drop out of [employment] when they get married and have children, whether they want to or not," so wanting a husband who can support them is simply sensible.
