If the boundary is lying......and your partner lies.....then you should end the relationship.
For everyone who says “it’s just a little lie”, I am genuinely curious as to where you draw a line … is it ok to lie about finances or food or alcohol?
To be clear, I don't think it's ok to lie about watching porn, but I think if that's a boundary for you and they then watch it then you leave and stop trying to turn them into someone who doesn't watch porn. She knows now that he watches it so there's no point in going back to what he said on the second date.
As I said earlier, cocaine would be a boundary for me, if I found out that someone I was seeing was doing cocaine I would end the relationship, I'm not going to forgive it and keep trying to make them stop doing it...and then act like I've been wronged every time he takes cocaine, when I have a choice to end the relationship.
I think it's fine to 'lie' about whether you masturbate or not though.
I've experienced an extremely controlling relationship which lasted for over a decade so don't think you can tell peoples relationship history by their responses on this thread.
Nothing makes me think this man is an abuser, If the same man was with a woman who didn't mind him watching porn then chances are there would be no issue, so it doesn't suddenly become abuse because he happens to be with someone who is against it.
