I get that feeling sometimes, and then I remind myself that my ex wife told her mother to book an expensive concert in her hometown in Thailand and that they would split the bill for the concert. Then my ex wife spent all her money on alcohol, clubbing, clothes, a new expensive cell phone, and gambling at the casino, and asked to borrow money from her mother so that we could afford the plane tickets to Thailand. After her mother had to already foot the entire concert bill after being told that she'd only have to pay for half. And somehow I still think, sometimes, that I was wrong for telling her to be more responsible with her promises.
