MY sil to be is causing grief, or rather, my boyfriend is. SHe basically has slagged me off on Facebook with his ex then lied to my bf and said it was about someone else and he believes her. She bad mouths me to his family and friends so that they now have a low opinion of me. This all wouldn't be so bad if my boyfriend didn't gloss over what she does and attack me for being upset. I don't think he sees what she's like. SHe's lovely in front of people but makes sly digs at me all the time. Or she'll offer my kids stuff they can't have just so I have to be the bad guy to them And tell them no.
Now she wants to take my daughter out for her birthday and I'm not comfortable with it, partly cos I don't know what she's going to be saying to her (in the past she's talked about inappropriate subjects with her), and partly because I don't see why we could indulge the whims of This person when she behaves like she does. My boyfriend on the other hand insists that she's his sister and I should be more tolerant of her for his sake.
Their parents split when she was young so he's always looked out for her etc.
I know that for his sake I should let my daughter go and have some time with his sister, but It's really irritating me what she does and how he doesn't seem to have any loyalty to me.
