“I don’t know how to break up with him”

I don’t know if I should break up with my boyfriend. I love him, but it feels like everyday we argue over the smallest things and it always feels like it’s gonna end, it never does but I feel like we just compromise to get over it and not really talk about it. He also talks to a lot of girls that he says are just friends but he once had a thing with before us, and I can’t help but be scared and I tell him this.

Also, I really need someone who would be willing to at least look into my church but he said he won’t convert and that’s kind of a loss for me.

I also have this weird feeling that if we stay together he’d be my last person I’ll be with, and I just feel like I need a get more dating out of my system sorta. I don’t know what to do. We’ve been together for almost a year which I know, sounds kinda stupid but it’s been bothering me.
