Is this the time to get rid of a friend/sis?

This is a conversation between my sister and I. She is not blood, but family isn't always blood, especially in my case. After this conversation, I did cut her off for a while, but certain circumstances in her life made me open the door again. After letting her back in, I found out that I was pregnant and when I told her she responded by calling g me an old geriatric pregnant woman that will be high risk and nine times out of ten because of my age I wouldn't be able to carry to term and will lose the baby. I didn't want to take it as she was being negative, but there was no other way. I cut her off again and then received a call that she was in the icu burn unit. She had me listed as an emergency contact, so her it is again another circumstance that happened in her life. Shortly after that, all was kind of getting back to normal with us until New years Eve when at a party I was physically assaulted. When she and I spoke, I told her about what happened, and she told me I was overreacting and tripping. This man kept touching me, rubbing on my legs and just making me plain uncomfortable, and she told me I was overreacting. Wtf? She knows all of the trauma I have been thru from a child and how it affects me still. She said when she is out, men grab her breasts and put their hands up her dress, and she feels fine. Idk what woman wants to be touched by a stranger when she doesn't invite him to, but she told me I was wrong because it was a party and he was probably drunk and was wrong for telling my husband. My husband approached the man and asked him why he touched me, and it resulted in a fight. I know that things do come to an end, and I have thought of ways to either see if this could be mended and I have not come up with any. My husband told me that she isn't my friend and never was and to let her be. I have done that. Would you Queens consider this toxic or not? For me, life is too short for any negative bitter folks. I need only positive people in my life who inspire and motivate me, not question who they are, friend or foe.
