I think to expect any sort of penalty or reconpence for adultery from the state is unrealistic in a legal sence.
Looking at it trying to see the best way possible to aid those who have suffered mental cruelty, torture and abuse through infedility is probably the only way to increase societies dissaproval of cheating as just a sport or an excuse for re starting new lives.
I don't think I could think of another abuse which is ignored to the extent that infedelity is.
It is minimised.
Until it is recognised as a highly toxic abuse that leads to great mental and physical damage then nothing will change. Reparations in the form of financial aid, disabilty aid and emotional support as any illness would require, maybe should be the way, but there is not the monies for that, shaming people for disabling their partners into un functionality.
For some it may not be nescessary but for many it really is a very real illness.
Maybe if there were more truths accepted by the state, such as recognising the victim instead of carpet sweeping then there maybe a more possitive shift in understanding and sympathising how difficult and hard to is for a person to overcome this injury, an injury that rarely is just about sex.
One thing which would be possitive would be to remove their need to be constantly defending themselves in how hurtful/painful it actually is to other groups whereby it serves their pupose to minimise it. If it was official then they may feel more protected..
I've known people become seriously ill after betrayal and never recover, their losses can be huge and often are, yet it is treated with contempt if they complain, the victim blaming is high and unnecssarily cruel. As a society that tends to look out for victims, in this particular area it seems to be sadly lacking.
Most betrayed people do not want to hear the other side, the reasons the excuses and nor should they have to, it is separate, it is for themselves to quantify their own guilt but this argument does nothing for the hurt party, the hurt party needs acceptance that gross misconduct has occured and for there to be help available.
Sadly I do not think there is adequate help available for such victims and unfortunately that leads to some very distubing outcomes, which predictably are also swept under the carpet by society.
In fact I can't see much help that is available, support wise it's a very issolating experience and financially crushing in most cases, it seems the shame is here to stay with the victim, you only have to look at these boards to see how victim blaming it is.
