There were a number of smallish but coinciding factors that happened which caused me to leave, it was a combination of...
The 7 year itch.
Spending 5 weeks back there in the summer of 2018 where the weather was hot and sunny every day, very rare in the UK, also the world cup was on and England were doing well, there was a good positive feeling in the country because of a combination of those two things and i had a fantastic 5 weeks.
A failed relationship with a Thai.
My job was stifling me a bit.
It wasn't a 100% "i have to leave" certainty decision, it was probably 60-40ish so i knew it would be tough and i would miss certain parts of my Thai life.
What i didn't realize at the time was just how much i had changed and grown by living in Thailand for 7 years, after being back for a few months the honeymoon period started to wear off, by six months i thought i may have made a mistake, by a year i was certain.
I had some bad luck/timing financially due to the pandemic and lost a big chunk of the house money.
The amazing things about living in Thailand had just become normal to me so i took them for granted, the terrible things about living in the UK had been forgotten about.
I take full responsibility for all my decisions but honestly if i could turn back the clock four years and have a word with myself i would in a heartbeat.
