I think whether or not you can remain friends with your ex depends or why you broke up. If you broke up because you or both realized that you just weren't in love, or weren't each other's type, its possible to remain freinds, because you basically are having the same relationship without the pressures of dating. However, if you broke up because you find out one or both have major flaws, or are immature, etc... it is almost impossible to remain freinds, because you had to share a creul honesty with each other that can even be tough for family to survive. Because JW's are cautious going into relationships, we often break up because of flaws, and so its more common for the friendship to die with the relationship.
