I haven't changed the premise as it was always two-pronged. And my question was never about the technical definition of the word 'cheating', but rather the moral implications thereof.
In a situation where one partner has stopped being intimate with the other, then from the POV of the partner being cheated on, I don't think they have any right to the moral high ground. And I fail to see how they can be outraged that the other partner got it elsewhere, when it was their own fault that partner couldn't get it within the marriage. In fact I'd posit that was appears as moral outrage is just bitterness at having lost the power.
From the POV of the cheating partner is where it gets more complex. The simplistic view, which seems to be the predominant one here, is that they should first leave the relationship before pursuing sex elsewhere. And I don't necessarily disagree with that, but I think it's more complex and nuanced. After all this partner isn't the one who unilaterally changed the situation, so why should they be the one to suffer?
Imagine uprooting your life and moving across the country to work for a company with a promise of a long-term job, and 18 months later they change the entire nature of your work. Yes you can leave, but to what? You've made major changes in your life for this job and perhaps given up many things, so now what?
Leaving a marriage isn't something you just do willy-nilly, and it comes with much stress and financial costs. Not to mention minimum 50% restrictions in seeing your kids. So the choice of leaving isn't really a choice, and men/fathers are just as much trapped within the marriage as women.
As to those who have a problem with me seeing marriage as transactional, hello, every relationship is transactional. Why are you together with your other half? Because you love them? Unconditionally? Are you saying if they stopped providing for your needs (whichever ones you have met in the relationship, emotional, financial or whatever), you would continue to love and care for them just like before?
I'm not talking if the OH became incapacitated or ill, but just because they can't be bothered. Is anyone seriously saying they would still be loving and giving, because after all it's not transactional?
Marriage is loving and giving, but of course there is also an expectation of reciprocity.
