Just that really!
me and DF have known each other for years, and she has a sister who’s around 5 years younger than us (we’re both early 30s).
for the past 6 months whenever we plan something, such as a meal, drinks at a bar, a night out, DF will invite her sister. The thing that bothers me is that DF will be a bit underhand about it, and tell fibs such as “oh no, I accidentally slipped up and mentioned we were going to xyz, and DS really wants to come!”.
This has happened so often that it’s starting to get on my nerves, as sometimes I’d like to spend a bit of one on one time with DF! I push back most times, I’ve told her that I’m happy to rearrange so she can spend time with her DS, or I’ll say that I was looking forward to us having a good catch up (as she sees her DS all the time!) sometimes I’ll just go with it and stop acting like a brat, but I never enjoy myself when DF’s sister is there. I’m not the biggest fan of her DS so I don’t want to spend the little free time I have with her.
another frustrating thing that bothers me is when I do agree to go when DF’s sister is there, DF acts really different. Whenever she’s around her sister she acts more like her, a bit mean (not to me) and immature. I might not understand the dynamic as I haven’t got a sister, but surely you can’t expect to always spend time with them and butt in on their time with friends??
the dynamic has really changed, and it feels like every event me and DF plan now her sister will be invited. I’m an introvert so I’m not the type of person to think “the more the merrier”, especially when it’s someone I don’t particularly like very much…
On the off chance that me and DF plan something alone she will keep it hush hush so her sister doesn’t find out, which makes the whole thing seem very cloak and dagger.
what would you do? Suck it up, or keep pushing back? And is this normal behaviour for those with sisters?
