Never have I ever...

They’ve been on and off for the past three years.  When they love each other, it’s the best of times, but when they hate each other, it’s the worst. 

Theirs is a passionate, sporadic love that can go from hot to cold in a matter of seconds.  Their friends think they should just end it, and many times, they might agree. 

But for some reason, they both keep coming back for more.
