Old pals are off to Paris without me and I feel left out

I'm quite bad at keeping up with old friends and I think the chickens are finally coming home to roost.

- 

I'm the kind of person who focuses on what's in front of me, so I put effort into friends at my work or other mums at nursery and school - the people I see day-to-day.

However I have a couple of groups of old friends from my school and university days who I love but don't contact much.

Over the past few months, it’s come to my attention that these friends still see each other quite a bit and have WhatsApp groups I'm not a part of - and I'm feeling quite left out.

I bumped into a friend from uni recently and it came out that she and a bunch of others are all going to Paris together next month.
