Ex wife and Fiancé in same car

Ex wife and Fiancé in same car

So my fiancé flew with my two boys today. It's their moms turn to have them. (she gets 5 weeks in summer, even years Christmas and 1 week during spring break) Ex wife drives fiancé to the ferry after they arrive. Fiancé calls after she gets dropped off. My boys made fun of their moms boyfriend for most of the car ride.... The man she cheated on me with 4 years ago (which of course the boys don't know happened). I shouldn't care, but it's still funny to me.
