To think she should return the favour?

[wtfdoidonow2]

I often invite my sister out with my friends and I. She always accepts and is affronted when rarely I don’t. She had never invited me out with hers despite me saying I would be keen to join. Aibu to think this is odd and to want to get to know them?

For context we are the same age and have similar types of friends so not like drastically different crowds. It’s like she wants my friends AND her friends but wants me to have only my friends. I enjoy socialising and want to widen my pool, am a sociable and friendly person with quite a lot of friends. Aibu?

If you are more outgoing than her, perhaps she's afraid you'll "steal" them. You sound very young

Favours should be given freely and no reciprocation required. If you don't like it either ask her directly to come next time she's goes out or stop asking her to come.

I’m not that young!

I am outgoing but would never steal them

She just makes excuses when I ask directly.
I don’t invite her to be invited out and obviously give the favour away freely! It would just be nice to be asked once in a while...

She now expects to be asked and becomes very passive aggressive when I say no, I’d like to see them alone. I went on holiday with friends last year and she asked to come along, she expects it now

Just say no and ignore the passive aggressive stuff.
