When I was growing up my friends and I used to joke about banging or ending up with fat chicks or marrying some chick who wouldn't work. Instead she would sit in her ass all day eating Bon-Bons, then complain when you called her fat. Not much has changed...
When I moved to Thailand, I broke up with a very cute real estate agent 6 years younger than I was. She was cute, had a nice body, treated me well, but I felt the relationship wasn't going to progress into marriage so it wasn't difficult to make the break.
