Keep the Ex's Name?

My husband and I were talking about this the other day - keeping your ex-husband's last name after a divorce.  Would you?

The only way I would keep a husband's last name is if we had children together.  So, if hubby and I were to divorce, after having four kids together, yes, I would keep it to have the same last name as my children.  If we had not had kids together and we divorced, I'd go back to my maiden name (not that I like my maiden name - at all - but there'd be no reason to keep his last name). 

My husband was briefly married really young.  It lasted about six months with no kids.  He went so far as to not just divorce but to annul the marriage.  She kept his last name (making it different from her kids she'd had previously).  He doesn't know why.  It doesn't bother me that she kept his last name.  I've never met her personally (saw her once from a distance), she's never caused any problems for us, and has no meaning to me whatsoever, so why should I care that there is somebody else running around with hubby's common last name?  I don't. 

However, I am VERY GLAD the ex-girlfriend he had kids with doesn't have his last name.  She wanted it, badly.  When we got engaged, she went to his parents to whine about it.  She was extremely ticked off when he married me when she couldn't drag him down the aisle kicking and screaming.  Maybe it's spite, maybe it's the last 15 years of stress and chaos dealing with her, maybe it's all of the above...whatever it is, I'm glad I'm not sharing a name with her.
