POLL: Do you believe this is a sign of future domestic violence?

My sister is currently in a relationship with a man she loves very, very much. I have never known a person to be so incredibly mesmerised by their partner.
Her partner is so cruel to her sometimes, he swears at her terribly and calls her shocking names, things like Sl*t, Wh*re, Mo*e, Idiot just to name a few, and those name generally have f**k and C**t at the beginning and end of the sentence.
He flys off the handle sometimes for no reason, and when she queries him about it he tells her that she deserves it and she leaves him no choice. This has left my sister an emotional wreck, sometimes she doesn't even do anything wrong, but she still thinks she deserves it and wonders how she as "disobedient". he then tells her he doesn't want her to be submissive, hypocrite!
If she doesn't feel like having sex he gets really mad and makes her feel like a whore.
He threatens to hit her quite often too, which has me very worried.
Do you feel all these are signs of future violence?

Also, she has been left with no self esteem whatsoever and he gets angry at her because she is so amazingly depressed and withdrawn.
He has even told their baby girl that her mum is a Sl*t and plans to teach her this as she grows up.

Future domestic violence??? It's that NOW! If you want to help her, get her the book "A New Earth" and see that she reads it. She needs a reality cheek. There is no love here just misguided labels. Abuse is abundant and she needs to wake up before it's handed down to her daughter and the cycle will continue. Her daughter will find a man just like her father.
He is a sick man. He won't stop and it will escalate. He'll need new ways to torment her.
She's wasting time and emotions with a man who will only suck her dry and may eventually damage her that she may never recover emotionally. Or even worse...
Life can be a beautiful experience. She needs help.

no one should be called any of those names especially the c word. he flies off the handle and she leaves him no choice? he can choose not to fly off the handle and not call someone names. yes these are signs of future violence. self esteem is something you give yourself. no one can give that to you. if you can get her as far away from this guy.

This is emotional abuse and is the beginning of the end. Please contact your local women's shelter and try to communicate with her this fact. Do not be pushy about it, just learn all you can and give her info. She will not leave until she is ready.
