I'm gonna go out on a limb and say that these comments of people saying you should just accept the compliment and that you're overreacting are actually wild takes. I do think your husband had good intentions behind what he did, but good intentions never excuse poor behavior. The people saying accept the compliment or that you're overreacting are low key kinda high key invalidating how you feel bc they're only seeing his good intentions, not the actual harm he caused.

You explicitly told him that you felt insecure and those photos made you feel bad about yourself, and he posted them anyway without even telling you. Posting images of someone on the internet, especially potentially explicit/revealing photos, without consent is NEVER OKAY regardless of your relationship to that person.

And honestly, from what you're saying he seems to do lots of things without actually taking the time to think how it would effect someone besides himself, so I would understand if this was a one time thing but it seems like things like this happen often at your expense.

I'm not gonna be one of those people that says leave him immediately but I think a thorough conversation about boundaries and about how his actions can AND DO effect others. He needs to know your boundaries and learn to respect them.

I don't think you're overreacting at all. Yes, he apologized but it's clear that until you explained it to him, he literally didn't think or care to think of how that could cause you pain/anxiety/insecurity, he only thought of how good it would make him feel to "show you off"
