I'm going to shame my girlfriend for posting a picture on Twitter.
Why would you shame her for that?
She shows off her body online too much.
While it is understandable to be upset if you think your partner is being too revealing and flirty with attention online, it's wrong to try to get back at them in retaliation. Shaming your partner isn't appropriate and will only cause her to resent you and act out even more. You should talk with your partner about how her online posts are making you feel and try to resolve the issue constructively.
I'm going to do it anyway!
I really don't think shaming her is going to do anything but cause more issues.
