I don't know what to do. My older sister has been in a relationship for a long time with a guy that no one in our family ever really liked. They have been living together for about 7 years & have a three year daughter. over that time DSis has gone from being an outgoing person who loved a laugh a nd a drink and a night out to being really unhappy. He is always finding fault with her (what she wears, how she talks etc). A few years ago he made her move to a different town because of his job and she left behind her freinds. Ever since then she has been miserable, but he says they can't move back because of money. He earns ten times what she does so this cant be true.. And it turns out that doesn't share any of his salary with her, even for groceries etc? I just cant believe that and I only found this out in the past year or so and I have been really worried about her since then. Anyway now she has just told us he's having an affair with a woman he works with (I think his boss?) for the last six months. DS told myself and DM about this but told us not to tell anyone. Instead of being angry DS seems to think it's her fault becuase she was spending too much time caring for her little girl and not enough time with him 🙄 I just can't understand this way of thinking. We live a few hours drive apart so I don't see her that frequently but every time I do see she seems to be in a worse state. DM and I have no idea how to help her see this guy is no good for her, and her life is so much worse with him in it, she just says she loves him and hes a good dad etc. What can I do to help her? Does anyone have any advice or been in similar situation? I am so worried for her
