Over here its just a convention. I did not want to get married but was pressuered into it by my ex family as they thougth our 2 daughters needed a "name" but they have my ex's surname. I resisted my ex MIL for a ffews years but in a manic state I thought getting married might solve everything. My married name is stupid and even my ex said they used to get teased at school for it. I only got married because my ex said that he could change his name but said that he meant he could but he wouldnt.
