Is AUTHOR wrong in the post ? POST : I’ve been dating my boyfriend for a little over a year. I get along great with his little sister (she calls me her bigger sister), his dad and I are friendly, but his mother and I have lots of tension between us. 

I’ve never been outright rude to her, but I’ve stopped making an effort to talk to to her. I say hello, goodbye, thank you, etc. only very basic things. But I’ve stopped all efforts for conversations. This is because of how she’s treated me the past year.

Everything was fine at first, but after a few months it got messy. See, they all speak Russian with each other (they’re all fluent in Russian and English, and have been in America for 13+ years). One time she noticed I looked a bit uncomfortable when they were all speaking Russian (I was sort of sitting there looking around, I didn’t understand anything, so I couldn’t add to the conversation). She turned to me and said “I think this would be a lot easier if you spoke Russian.” 

Now, I 100% understand why they speak Russian, it’s their culture. But telling me it’d be easier if I learned a new language? Easy for who??

Anyways, after that she started getting more and more cold to me. She gives me dirty looks sometimes, it’s just clear she doesn’t like me. One time she even told my boyfriend to his face that she thinks I’m “fake” because she can tell I dislike her, but I’m still nice to her. I do this out of respect, I’m not going to be rude to her when she allows me to go over to her house. 

I’m at a loss, I wanted to be close with her, I’ve always been very close with my boyfriends parents, but I’ve just stopped trying. AITA for no longer putting in effort &amp; for totally resenting her?

ADDITIONAL INFO: I’m my boyfriends first girlfriend. At first my boyfriend thought she was being protective, but we’ve been together for about 13 months now. My boyfriend now thinks maybe she resents me because of arguments she’s overheard between us in the past, but we haven’t really had a rough spot for 6 months, and she made the Russian comment to me long before we ever even got into an argument. So I don’t think this is actually why she dislikes me.
