idk anymore helppp

sooo. I been dating this guy for a month, we didnt argue much and we were doing absolutely great, like he would tell me he didn't want to have to date any other girl than me again. I was born to Christian parents and religion is very important to me. Last week, my (ex?) bf just said some shit under his breath. btw,hes not religious. We were talking bout marriage and everything and said he doesnt want to get married in a church and his children won't be baptized (i'm the total opposite you know), and shit just went down from there, everything escalated so quickly and at one point, he said: well your God is a psycho, and I don't wanna have anything to do with him. right. He also said religion was bullshit and the church and the pope were the devils, like who the fuck would say such a thing? and he even made fun of how skinny I am and he just went too far. ok so the days following that, I was sooo pissed and hurt (I told him but he didnt seem to give a fuck), and at some point, when I got more and more distant and would text him less than before, he tried to apologize and I was like yea its fine blablabla..(i was just so done with him and that). we even wished each other to find a better person. and it was kind of awkward after that, he tried to flirt with me again but i litteraly had already lost all interest in him. and just yesterday everything was fine, i just acted neutral, we would talk normal again. and i came over..we had sex. and I feel like I'm in love with him again..but if my parents ever knew all the horrible stuff he had said to me when we were fighting, (they havent met him yet), they would just tell me to cut him off from everywhere and hate him. anybody ever been in such situation? 😔 idk what to think of it anymore. we both said we wanted to stay single for a while but he still acts like my bf when weretogether..
