<human>: My SO will be Jane, her mother Tanya and brother Ryan.

I believe the line between compassionate behavior for a family member or loved one has been crossed and is now and likely has always been this way for Jane. Instead of compassionate behavior, I believe Jane is enabling her mother and brother to abuse her.

Examples of abuses I have personally witnessed include, threatening to burn down the house, constant negativity, asking for tons of favors while doing nothing in return and becoming angry if her demands are not immediately met.  As well as physical abuse including punching, tackling and throwing things at people. Tanya has also tried to verbally attack me, however she stopped once I stood up for myself. It's not about me though, its just an example of her being a bully who will back down when confronted.

Jane will not stand up to her mother. She continues to jump for Tanya's demands, including demands for money. Not that Jane and myself are destitute, but for that matter neither is Tanya, but we definitely don't have it to lend to someone who may or may not have any intention of paying us back.

Ryan is in and out of jail and drug court and rehab for his addictions to everything he can put in a needle and in his veins. He lives with Tanya when not away, doesn't work, is useless and a sponge. I think everyone knows the type.

Am I being unreasonable asking Jane to stand up for herself and not cave to her every request? It hurts me to see her treated like that. Jane and I have talked about this seriously at least 4 times. And she seems to always agree with me, but has yet to do anything different.  I always express my support for her and I haven't cut ties with Tanya. Jane and I still see her often. Jane visits her more than I am willing to, and I my be wrong about that. Idk.

Would it be wrong of me to stand up to Tanya for Jane? My current feeling is that Jane would not appreciate me getting any more involved than I am already, since I am not even sure Jane realizes the level of abuse she receives from these people.

Can you summarize the given text in a few sentences?
<bot>: Is their anything else I can do to help my SO to stop enabling her mother and brother from being abusive towards her?
