So your significant other should be able to do whatever they want without any boundaries? Obviously there are things you're okay with in a relationship, and things your not. If you said you wouldn't want her posting sexualized pictures on social media, and she does it anyway...it's grounds for potential break up is what I'm getting at. Some people just "let" their girlfriend do it anyway even though they are clearly not okay with it. It's the same as "letting" your significant other communicate with their ex on a consistent basis...some people will be okay with this while others would have previously said they are not okay with it but still "let" them do it anyway.
