how do i (19f) break up with my (19m) bf?

Around June, I noticed he was interested in me, and since no one had ever shown interest in me before, I rushed into a relationship with him. At first things seemed great, but only a few days in, he came to my house. I had planned for us to just watch a movie and relax, but halfway through he said, “I brought a condom so you can suck my dick.” I said no because we had barely been together for a week, but he kept pressuring me and I eventually gave in after he told me, “That’s what couples normally do.”

After that, I didn’t see him the same way. He kept pushing for more even though I said I wasn’t ready. That same weekend, he introduced me to his parents, which felt way too fast. After that i started to put some distance between us by telling him i was busy or not replying at all so then, he showed up at my house unannounced, and in front of my mom, and since she wanted to meet him she invited him for lunch and then he brought up something his mom had said which was that both our families should meet but I told him later i did not want them to since again too fast is been like 2 weeks at that point but he still tried to talk my mom into it but my mom quickly shut it down sensing my unease.

Since then, I’ve been wanting to break up, but I can’t find the courage. He tells me I’m his whole life, and he and his family act so happy that it makes me doubt myself, even though he makes me feel bad. There are more incidents, but this is too long already so my question is how do I find the courage to break up with him? i know i want to i no longer feel comfortable with him
