A relationship that was rocky, had multiple breakups or included abuse is not a good foundation for friendship. Even if things end well and amicably, there's those lingering feelings of chemistry to ponder. Is there a chance that you'll be out drinking with friends and hook up? That scenario may do more harm than good for your well-being. As long as there's no passion left between you, things are probably safe. There are instances in which it's beneficial and even advisable for you to remain friends - or at least civil -- after a breakup. A botched workplace romance can create serious tension at the office, which can be detrimental professionally. Obviously if you have children with your ex, you want things to remain civil among the two of you for the sake of the children, who've probably already seen their share of their parents fighting. If you're breaking up, really consider the meaning of those four words - and if being friendly will work for you.
