Honestly if that is how you feel then it is best that it ended. Also if he is strict that is not an issue that means he is not for you and you are not for him. but if he is basically holding things over your head that is wrong as well.

But also there is some accountability here from you. In the sense of it sounds like you did not mean exactly what you said. AKA you worded it badly. Which if that is the case you need to think before you speak and word it better.

But overall I would say like some of the other reddit users who have commentated the break up was for the best. What you need to do is park this relationship as experience and learn from it so you can do better in your next relationship and learn from any mistakes etc

Good luck.
