I agree with you Valeria - while we need to accept people for the way they are, the same applies to them. I need to be wooed and won by any prospective partner - not in a Hollywood way, but by acts of kindness and understanding.
The OW are so easy to 'win' and so hard to live with. I like to think I am the opposite.
And frankly anyone who cannot see that they might have done a fair bit of damage really hasn't 'got it' This is not the same as 'punishing' them. There is a wonderful line in the parable of the Prodigal Son, often overlooked 'When he came to his senses' he started the journey home. He repented, and 'his father saw him coming a long way off and ran to meet him' These are the two crucial elements. We have to meet them, I agree, but they also need to show they are sorry. There is much to be sorry about. It is pointless to gloss over that.
