2 weeks ago my DSis messaged asking if we would be able to meet up as my family haven't seen hers for 18months or so. I replied back that we were free in August anytime after the 6th and asked when was good for them. She read the message that day but never replied. Two weeks go by and I message asking if they were ok and has she got any dates as we have other things to organise in August too and that as she has had two weeks hopefully she'll know what she has planned for August by now. She has got shirty saying I was rude and should just go do my other plans. I said she was rude for leaving me hanging for 2 weeks with no reply. Now I'm questioning whether I was rude to call her out on leaving me hanging or was she rude for not replying in the first place? Not to drip feed but she has not been to my house for 4 years, we always travel to hers (2 hours away). She also goes months without making contact and it is nearly always me who makes the first contact. Does she just not want to really meet and was just making pleasantries and I should have got that when she didn't reply for ages?
