but it doesn't seem to be relevant either
women aren't private property like a car and she is free to chose whether to be with him if she wants to or not - there isn't necessarily any 'wrong' for the OP or this girl to be responsible for in the first place providing she is then upfront with the 'boyfriend' that she has found someone else
I should have known better than to use an analogy, since it provides a perfect opportunity for people to ignore the point and talk rubbish about the analogy instead. You're the only person who has made any comment about women being property, which is a such a bizarre connection to make that I am suspicious that you're using it as a strawman.
You are also the only person who has created a scenario in which someone ends one relationship to start another. That is a completely different scenario.
So I'll try again. If you disagree with
anything I've actually written, feel free to reply. Even if it's just "you're wrong because I say so", that would be a huge improvement.
If person A is in a monogamous relationship with person B and chooses to have sex with person C, I think that person A is responsible for their choice to do so.
If person C knows that person A is in a monogamous relationship with person B and chooses to have sex with person A, I think that person C is responsible for their choice to do so.
I think that person A's choice does not stop person C being responsible for their own choice. Both person A and person C have chosen to breach the terms of the relationship between A and B.
So which part of that do you disagree with and why?

Read Dowie's post - she's free to do what she wants, just as the OP is. Would I do the same? No. But that's not to say what she wishes to do and what the OP wishes to do are wrong. You have an opinion, and you've made it clear what it is. But your opinion IS NOT a rule that the OP or this girl have to abide by!
Obviously, that is true. I am not absolute dictator of the world, nor would I want to be.
Other people can have the opinion that cheating on a relationship is fine. They are free to do what they want, including that.
I was answering a question from Roar87, specifically this question:
Why should the OP respect her relationship status if she's made it apparant she doesn't?
Because the OP is responsible for his own decisions, just as she is responsible for hers. Her decision would not remove his responsibility for his own decisions. Why do you think it does?
