Should I Break Up with Him????

So me and my boyfriend have been together for 2 years and 7 months. Well we are both in our senior year of high school. So we have a really good relationship but we have always struggled with one thing. I always had wanted to wait till marriage and he had lost his virginity in the 8th grade with his ex. I know. Well when we first met I specifically told him that I wasn't going g to do that with him. But.... when I had turned sixteen we did it. I regretted it because I felt so bad that I had promised my mom that I wouldn't do that till I was older or married. I felt so much guilt!!!! I cried because I was so embarrassed that I thought I would never do it in high school but I did. he always would say stuff like well I don't want to wait and it would hurt me cause he couldn't wait for me. So we would break up but he so perfect besides that. And I know it might not last forever but I always hope there would be a chance. My family loves him. And I am really happy with him. So finally we came to an agreement that we would wait until we are older or wait till we were married but everyone we were alone. we couldn't help it. sex is amazing. And I would always feel so horrible after and still do. But he is always saying he will wait but then once it starts getting hot and heavy he immediately is ready to do it. sometimes I think is this what I want for the rest of my life. I'm young so I know it won't be the end of the world but it will be hard since he was my first and it would be nice to think that I married my first. that would make me feel better. I just told him like an hour ago that I kind of want to break up and he cried. it always gets me. But please give some advice I don t know what is best for me . He isn't a bad person but just a human.
