I haven't read the book but have binged all episodes over the last two days - I loved it - very bittersweet
It mirrors my first real serious love at 18, our 'real' relationship lasted only 3 years until he went off to Uni in another part of the country and long distance in those days (early 90's) just couldn't sustain endless coach journeys and no money.
We're both almost 50 now and the intensity of our relationship has tarnished any future relationship we both have, we're both married to different people and have been for many years and have children but we'll never love those partners like we did each other, we'll never have the same intense relationship with anyone else like we did with each other.
Sadly each time one of us was available, the other wasn't so many 'missed' opportunities. I really resonated with Marianne when she said, its just not the same with anyone else, it isn't and that's so sad - both in the programme and for me in real life, it isn't and never will be.
We have episodes when the reality of missed opportunities spills into real frustration and you can't tell anyone in real life that your heart really belongs with someone else, so you spend an eternity in limbo, its soul destroying. We drift in and out of each other's lives often the frustrations mean we fall out and don't speak for months, often years but we always find each other, he knows me better than anyone else and I miss him terribly.
I cried especially at episode 10 when he is talking to the Counsellor as we both came from similar family dynamics and his realisation of not being able to go back was something I went through too.
As I said, I loved it, it allowed me to go back to a time with fond memories and sadness and indulge in all that wonder that a first proper love will give you.
