I might be overreacting, I know - I am coming off antidepressants, I'm dieting and my period is due so I'm a bag of nerves and perhaps unreasonable. But.
I'm originally from mainland Europe, have been living and working in the north west for 7 years and DH works 90 miles away and comes back home at weekends. DS is 22 months.
We'll be spending our summer holidays at my parents' holiday property on the beach. DM (still working) made me buy a flight ticket for DF (retired) on our return flight, telling me that he wanted to come.
To me it was a good news, it would have been also nice to have some help with DS. But I was surprised - DF goes on everyday day about how he wants to see DS, FaceTimes us multiple times etc, but also repeats that we have to travel as he hates here - the food, the weather, having to drive on the wrong side, not understanding the language and so on.
Yesterday DM texted me that he changed his mind because "it's a critical time for his garden".
WTF?
She said he's probably scared of something and doesn't want to admit, maybe travelling alone (but in an airport routines are pretty established, you don't have to speak much) or that something would happen to him (he had 2 bypasses two years ago, but he's constantly checked and has come here with DM twice since. Also, it's unlikely that by July there will be already a hard Brexit cancelling the European insurance card).
I know I should talk to him directly, but I'm so disappointed that I can't face it atm. maybe after I've calmed down. Which looks unlikely until I can have some carbohydrates 
Should I just let it go?
