I have been with my boyfriend for 2 years. We live together and are actively talking about getting married. However, his sister is really rude to me. For example, she ignores me at parties when I try to talk to her. She declines every single invitation to have dinner with us. During family holidays/vacations where we are staying in the same house, she often leaves the room as soon as I walk in. When she calls and my boyfriend picks up, she demands he "take a walk" so I can't hear what they are talking about (mostly about fights she gets in with friends). Most famously, she sabotaged my turkey on Thanksgiving. She is 30 years old. However, I feel like I am being bullied like a middle schooler again. I feel very hurt and cry after almost every family party/event. My boyfriend asked her about why she is doing this and she didn't have any specific reason other than she just didn't like me. She said I was "too quiet," "nervous" and "awkward." She couldn't point to anything specific I was doing that she didn't like. I feel like I do get quiet and awkward around her because she makes me so nervous! I have tried to be nice and to talk to her and she rejects all attempts to get to know one another better. My boyfriend feels like she feels intimidated by me because I am younger, prettier, employed and get a lot of family attention that previously went to her since I am "new." Last night, she called my boyfriend about her birthday bash. She told him she wanted him to invite some male friends to her party so she could meet a potential boyfriend (to her family's knowledge, she has never been in a relationship). My boyfriend said he didn't really want to do that, but he would try if he could bring me along to the party. She said no. She said there were a limited number of spots at her party, that there were too many females and he needed to bring male friends, not me. My boyfriend feels she is being selfish and unreasonable, but doesn't want to do anything about it. He feels like if he pushes the issue, she'll just be more horrible to me. He said he just won't go to the party at all. I feel like it isn't just about the party, it is about a level of disrespect I don't want to deal with for the rest of my life. He went to consult his parents today and they said she had ALREADY called them to complain that he had even asked to bring me with him and ranted about how it is her party and she shouldn't have to invite me. His parents told her to cut this all out, but she refused. What do you think about this? This situation makes me feel so bad about myself. I haven't had this level of conflict with someone since middle school.
