"It's a bad idea to get caught up with trying to get someone back though. If you get over someone in order to become good friends (which is near on impossible) you won't want them back anyway. If you still want them back, you're not over them and therefore shouldn't even be attempting friendship." by equivo
I see your point. But i take a more positive approach. Which is, why should you loose a friend just because the relationship didn't work out? I'm not saying become friends to intentially get them back, but just be there, stay in touch, be there for her when she needs support and who knows what will happen in the future. But yes, being over the person is neccessary, otherwise you can't pursue a good friendship (Your feelings will always get in the way).
I think this approach is much better and more productive than just saying "That's it, from now on i'm never seeing her again", because who is really benefiting from that? And friendships after break ups do work by the way. And people do get back together sometimes. By the way, being friends with your ex doesn't mean you yourself cant pursue relationships with others! But it's CircleC's life, so the choice is really up to him...
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
