You people must be Joking. One of the greatest threats to marriages is an Ex, Many first kids to so many married couples belongs to their ex
You guys won't respect yourself Until you find yourself in deep mess, Nobody said you should start keeping malice with all your ex but common sense should teach you what boundary is.
