I am friends with most of my exes, they are like family.
Just because we did not work out living together (I know I am difficult) does not make them bad people.
Maybe my choices have not been so bad in the first place that I had to banish my exes from my presence for all time?
I feel truly blessed to have these wonderful allies and friends in my life.

and I think they would say the same.
I have heard the "Exes are exes for a reason" thing, but usually from bitter grudge holders.
