So me and my girlfriend have been dating for 11 months now. When we first started dating she told me she had anxiety, so I didn’t think much of it when I first brought her over and she wouldn’t really engage with my family. But now I’m starting to worry. She has opened up to my mom and stuff but her and my sister dislike each other. My girlfriend dislikes my sister because my sister is “disrespectful and rude and doesn’t know how to treat people”. Which is true she’s very rude to our mother and myself. Recently my sisters friend told my sister that my girlfriend has been liking a lot of her posts but hasn’t been liking my sisters, and my sister says it’s cause my girlfriend is trying to infiltrate her life and being her down. Idk. I ask my girlfriend to be nice and comply but she doesn’t. If we go out and my sister is there she’ll just sit down with a bleak look on her face and not speak. Then when I ask her to be nice and kill with kindness she freaks out and cries and says I don’t care about her or consider her feelings. My mom also pulled me to the side and says she’s just trying to divide the family. Idk if that’s true but I also could be blinded. She does come from a rough family life. I really just need help I don’t know what to do.
