Idk how to break up with my bf please help

I want to break up with my bf (it’s a long distance relationship) but I don’t know how, im too scared, he never theeatened to do anything to me but he has some weird actions, like sometimes hes very condescending but denies it, after i mention it he apologizes for it, he found my moms socials (?) bc i didnt want to tell him and it got stuck in his head, he pressured me into giving him names of some people in my life (i gave general names nothing he could do anything i think), and he gets bothered when i say im scared of him, even tho he says it doesnt bother him I can tell it really does. I keep having a weird gut feeling, but im too scared of his reaction if we do break up, (one of the reasons is he pressured me into sending him *those* types of pictures, he always said he would never but in the moment he did, it was always a one time view photo tho so there was no way for him to save them or screenshot but it does scare me a lot), he also knows my city but not my address i never gave it to him, but he knows how to doxx people even tho he never doxxed anyone. Our religions are also different ao we cant be together i found out a few months ago. I dont know how to break up im too scared but its consuming me. I need help..
