My sister lives about three hours away. I haven't seen her for 2.5 years. We both have children and I would like to have a relationship as we get on and my elder dd wants to see her cousins. Dsis has a record for being unreliable - we've made plans to go and visit her 5/6 times in the past 2.5 years and she always backs out with an excuse despite it being her suggestion. We've even been on holiday 5 miles away from her and she didn't manage to see us.
We were meant to go and see them this weekend. I sent her a message on Wednesday asking if it was still ok and she said they're decorating so can't do it now. They apparently can't travel to us as she says her eldest has travel sickness in cars. I've offered to collect them from the train station instead, she said her children would be unmanageable on a train.
Luckily I hadn't told my eldest that we were seeing them this weekend otherwise she'd have been let down and upset but dsis doesn't seem to consider this. I'm thinking of just giving up on the relationship altogether as she is so unreliable but part of me feels bad as her dh is quite controlling and I suspect he could be behind the cancelled plans. Last time we saw them he smacked their then 9 month old and I said something and he was furious. Aibu to give up trying?
