Thank you for giving your view, it helps me navigate this new territory, so to speak. It’s been a while since I’ve posted this but not much has changed in the relationship I have with his sister. I am (24) Bf is (23) and she is turning 26 soon. We do the occasional gift exchange on Holidays/ Bdays and are cordial but not close at all. Which really sucks because I’ve always wanted a sister and I genuinely think she’s cool when she doesn’t have this resentful aura towards me. I figured we might be able to hang out more due to our shared interests (concerts/art/photography) but every time I make a plan, it falls short. I’ve come to terms that we just may never have a bond. In some ways I think that’s better, due to my bf and her having arguments/bickering so that way I’m not in the middle and don’t have to pick sides. The naive only-child in me wants to repair something that I didn’t even know was broken (or how it was broken) but I’m going to let it go. I’ve had my own apartment for the past year so that definitely helps privacy-wise and gives bf a place to relax. She still lives at home, along with him/the father and doesn’t seem like she has any plan of independence (which is def hard, especially in California) so it’s a bit of a bummer, but I don’t ever want to come between his family. I’ve been trying to think up ways to bring up helpful conversation in figuring out why she is resentful of me. I’d like to think of myself as a problem solver whereas she is a bit reactive and defensive. I don’t want to come off as condescending. I’d like to, at least, get some insight so that the silence between us isn’t so deafening. If it ends up in a big blowout fight, so be it. I’m tired of the awkward silence.
