Boyfriend help

So i’ve been dating my boyfriend for about a year and he’s bought me gifts and taken me on amazing dates and just been a good boyfriend but i want to break up with him. I know he loves me and he’d do anything for me and im scared i’ll never find that again but I don’t think I love him the way he loves me and I dont want to waste his time when he can be looking for someone who actually deserves him. Also college is starting soon and hes going to Arizona and Im in California and I want to experience college single and plus im scared he’ll cheat while in college. Also im no longer sexually attracted to him anymore because for maybe 90% of the times we’ve had sex i had been pressured into it by him and i can say no but he’ll keep asking over and over again and i’ll finally say yes to get him to stop or if i say no he’ll keep touching me and wont stop. Also one of the major reasons is that he says he’ll kill himself if i ever break up with him and im really scared he will so I dont really know what to do. Any ideas??
