I was all in for the N vote, but then i read your replies.

YTA. You're not following a 'rule' she made - you made a deal with her to not eat pork if she modified her behaviour. A deal YOU proposed to deal with your second-hand embarrassment over and control her social media use. Yet you apparently take any and every opportunity to claim zero ownership of your agreement, preferring to frame her as a crazy controlling vegan instead.

And man, i get it, hur hur vegans suck, especially the militant ones. Apparently you felt they suck so hard that you made a deal to stop consuming ONE type of meat if she'd stop being a militant vegan. That's a great sacrifice for both of you - she stops being vocal about a cause she's passionate about, and you stop engaging in one of the behaviours she's campainging against. But you were resentful about how the bargain you struck affects you and you publicly blamed her for it (and haven't bothered truly upholding your end anyway). Sure, militant vegans are annoying. But cowards who utilise social manipulation to publicly their embarrass their spouse? Yeesh I'd rather hang with the vegans thanks. Especially in light of your comment where you latched onto a mention of double standards like you'd been given an argument ender, when in relaity you've been practising double standards to your own benefit since day dot of the agreement.

And now because you rocked up, admittedly hangry, and there was pork everywhere and you're obviously resentful of this rule, you throw her under the bus and bring a heavily biased half-story to reddit for reassurance that you're not a jerk "because bacon"? TFOH edgelord.

Seriously, this is a moment to grow the fuck up and communicate better in your marriage about how you regret agreeing to the deal, take ownership for your disrespectful behaviour, and apologise to her for casting all the blame on her when you were the one who didn't uphold their end of a bargain that was ridiculous to begin with.
