at37, when you leave or kick him out he is not going to let go easily.
Please stick around because thousands of us have been through this. He will promise to change, he'll show fake remorse, he'll use reason on you, he'll remind you that you're not perfect either, he'll make you feel like you've no right to end it with him, he'll make you feel like you owe it to him to give him another chance. Your head will be spinning.
I recommend that when you tell him it's over don't give him any examples such as "the time you roared at me for hours". That will instantly be flipped around in to your perceived failures, what you did to MAKE him roar at you for hours and how really he is a virtual saint to have put up with you for as long as he has, and how dare you criticise him when blah blah blah blah blah
Keep it as simple as you can.
Keep it as much as possible to statements that can't be argued with.
Pick about three or four and just repeat them over and over again and don't get drawn in to further discussion.
"I don't want this anymore"
"This is over"
"I don't want you anymore"
"I don't like you"
"I look forward to a future without you"
"I want to end this relationship"
"I am unhappy with you"
"I want to be single"
Start with the least confrontational. Like I want to be single. I want to be single. He will try every trick in the book to get you breaking it off with him switched around to be a conversation about your flaws.
Whatever ridiculous flaw he tells you you're guilty of just say ''I accept your perception of me". If he tells you you're evil and selfish and a cold-hearted bitch and you're cruel and you've ruined his life, don't defend yourself. Say like a lifeless sap ''I accept your perception of me". Don't even stress the your
Mantra
I want to be single.
This is over.
I look forward to my future without you.
I accept your perception of me.
Good luck breaking it off. You're going to need support breaking it off. You've decided that that is the right thing to do but a brain mincing fucker like this guy is not going to shrug and say ''no hard feelings at37".
I read a good article that helped me deal with my own x emotion-mincer. Drop the Rope. I 'll try and find it for you.
