The bit about screaming when you woke up to find him standing in your house was like a scene from a horror film.
First thing tomorrow morning get the locks to your house changed.
You are in danger. Do you see this yet?
His message about taking a break wasn't asking for a break, of course - it was a threat, designed to frighten you into panicking, begging, getting frantic with squirming anxiety so you'll say and do anything to 'get him back'. It was 100% a coercive controller move.
This is your chance. Your get-out. Grab this opportunity for freedom and peace of mind and the chance for a happy 2026:
Send a polite email (not text) reply saying 'In response to your message - yes, you're right, and I agree with you.
This relationship isn't working for me, either. I don't enjoy it and won't be continuing with it any longer. Time to call it a day.
Thank-you for the time we've spent together, and wishing you all the best for the future.
Please do not contact or approach me again'. (It's important to include that instruction in writing, in case you need to prove you were clear).
If any of his things are left at your home, add 'I'll package up your things and have them sent to you.' Don't agree to him coming round to collect them - you'll be vulnerable.
Ensure you and your dog are away from home when you send it - women and pets can be in danger when they slip away from an abuser's control. Can you go stay with family or friends?
