Not sure how to handle this

Been with my boyfriend for a little over a year. I'm starting to realize that I'm really not that into him. I don't think I ever was. I mean I think I love him. It's things that I can't about him. Like his anger. We literally been arguring since day one & every argument we have always leads to me me doin wrong (which I'm not & never did). Also may add that he has a slight addiction to prescription drugs 😭 he takes one like every night. It's so much behind this little confession but also so much to write. I don't know if I could see myself with him for another year
