You have realised this man is an absolute nutter?
A controlling, manipulative, abusive, misogynist wacko?
You were supposed to cancel your holiday and run after him pleading with him to forgive you and take you back. That did not go according to plan and his control slipped, hence the tantrums.
Do not get into wrangling 'oh yes you did oh no I didn't' back and forth conversations.
He will see and present his own versions of what did or didn't happen and will make up more scenarios in his head and twist you into a pretzel trying to make sense of it - if you let him.
You are not responsible for his mental health issues. He is.
Take a screenshots of every single one of his unhinged messages.
Send him a final clear polite message like
"Hello X. After a great deal of thought I have concluded that I do not wish to hear from or see you again. Please do not attempt to contact me in any way, visit or approach me, my home or my work. I wish you all the best for the future".
Don't answer any replies.
Block everywhere.
You've been with him a year. That's 365-ish days, nothing, really.
Be wary, be alert, be careful.
Move on, have fun, enjoy your trip and take your mind off him.
