Really tough one. Long. Will try not to drip feed.
Sister is the youngest of 3 of us. Always been attention seeking, but got a lot worse after drama school, where I think they basically inflate your ego to help you cope with all the constant rejection in the industry (understandable) and you also surround yourself with "yes men" who also have this ego problem so my sister and her friends just talk AT each other (about themselves basically and how wonderful they are).
Outside of this circle, she's not easy to get on with - dominates conversation, doesn't listen, interrupts, calls everyone unsolicited pet names, thinks her life is the most interesting thing and everyone will want to hear about it. It's not just me - my DH, friends, our brother, and her ex-boyfriends all have the same reaction. It's especially bad in groups but also 1-1. Massive over enthusiasm about everything so it comes across fake.
I just can't stand her but I know she's lonely and would like to have a closer relationship with me and our brother. She tries to reach out sometimes but I think it's like I've got to the point where the smallest interaction annoys me to a disproportionate level. I'm not interested in her career (by which I mean going to see her perform) while family make a huge fuss over it (she also thinks my work is boring btw, but I don't expect her - or anyone else - to take a special interest!).
I am sure some people will think I'm unkind / intolerant / jealous but as I said it's not just me who reacts this way to her. Family tolerate her and my mum indulges and fusses over her because she likes to feel needed.
At the same time I feel guilty and sad that we don't have a relationship and that I should try to do something about that. I even took her on holiday with me last year to try and bond a bit more but it just showed me even more how utterly self involved and rude she is.
Should I just park the guilt and be open with her that we are just too different and I'd rather just not have much to do with each other?? I can barely force myself to even make small talk with her these days.
