We live a 6 hour drive and 3 hour ferry journey from my mum (dog has to come, think she looks forward to seeing her more than us). I used to visit twice a year. Mum never visits us - last time was 7 years ago. Last visit (Oct last year) was stressful, mixture of unexpected hospital stays, me having to go look after family member for a couple of days, culminating in a fall out where I said wasn't coming back. Mum apologised and I've just arranged for us to visit for a few days in the summer.
Her response? Not good dates, work is busy at that time.
She works part time, should have retired years ago due to ill health and really isn't needed in work (extended family business).
The dates are the only ones which work for us, dp and I both struggle to get time off together.
I feel like cancelling.
