Is it wrong to take her off Snapchat?

So one of my best friends (or so I thought) has been going out with one of my ex boyfriends. And I'm not being a petty ex girlfriend but that guy is a douche and has sexually assaulted me before and she knows and is still with him because "she loves the way he treats her." She posts pictures of them together on Snapchat all the time and it irks me a little on the inside. Just seeing her with him knowing how he is....would it be bad of me to take her off Snapchat if it makes me uncomfortable?
