I'm a nice person - I don't go out of my way to be mean to other people. When my FH and I first started dating, his sister went out of her way to not be inclusive. The unofficial scapegoat was that I didn't have the ring yet and I was just a girlfriend. Once I had the engagement ring, she had to be cordial to me. FH says our interactions seem weird but you can't force closeness, especially when someone hasn't been kind to you these past few years. I'm accustomed to being good on my own and have mastered the art of not taking it personally when someone tolerates you - NOW suddenly they expect me to be friendly? You can't force closeness over someone who has never made you feel welcome. I also thought it was very self-centered & entitled of her to assume she was part of wedding planning when we'd never have a close relationship - she's entitled because her brother is getting married. His own mother doesn't behave this way with me. His sister (at the beginning of our engagement) said, "i wouldn't be offended if you didn't include me wedding planning" ---> who said she was included in the first place? When she was getting married, she was so cold towards me and mentioned NOTHING. I didn't even want to ask her.
Like I said, within the past year and a half, I've been comfortable and have become secure/confident without her approval. Older women have told me she has jealousy issues but that's honestly none of my business or my concern. She's a grown adult and is responsible for herself and her feelings. I'm sure once the wedding hits, I won't even notice her but she's such an attention entitled person. She was sucking up to me to have her baby included in the procession but she's still too young. She uses her baby as bait to get more attention. She doesn't know how to be happy for anyone else, including her brother (unfortunately),
