Dora is not the type of character who stands up at all. The problem lies deeply to the roots, the way how she was raised. I can also understand the behaviour of Jack towards her. He used to insist her to stand up, but she would never do that, she would rather lick the feet of that woman. That is why Jack being frustrated treats her like sh*t
To be honest, Dora deserves this treatment. If you allow people to trample over you over and over again, you deserve to be hated.
And if you are wondering about musician guy, he is an outsider but he is smart and knows his boundaries. But I am not putting my hopes on him though.
