At first, I don't understand the question, until I read the responses. Well, it is possible to be friends with your ex? Yes, I think so. With maturity sakes and for the good of all the good memories you had, you can be friends with them. Being friends with people have levels. Maybe you can be friends with them like you will talk about your plans or some of your history, but not to the point that you will go on the date with them, unless when you are with a bunch of friends. Some ex's are friends because of their children. They need to be in good terms or decided to be friends because that is what their children wants. Also, you need to forgive each other so being friends is another chance to be at good terms with them. I had learned lots of friends who are ex's but they are good friends.
