Do I [17F] break up with him[17M]?

I [17F] and my boyfriend [17M] have been together for about a month however we've dated twice before where I ended things, after the last time we started ignoring eachorhers presence despite having mutual friends causing me to migrate to another group I left that group of friends bc they were toxic about a year ago and found my way back to my old group somewhat he was part of that little group. Recently about 3 -4 months ago we became friends again and then about 1 month like not even two weeks before we got together again we became really close friends. Then we were somewhat flirting atleast I was and my friend asked if she could find if he likes me I said I dont really care you can if you want then we were talking and he said he wanted to take it slow this time and not tell anyone, i thought he meant for the rest of school break I was wrong, then I started realising maybe I didnt like him like that maybe I mistook friendship for attraction, because imma be honest im not physically attracted to him, anyway I relaiesd he jsut wasn't my type but I didnt want to break up with him and ruin our little group of friends so thought to give it a week or two. Fast forward to now and last night he texted me goodnight but said I love you. I was taken aback because I thought we were taking it slow and he said it again today . I dont know I dont think I like him like that but I dont wanna ruin our friendship again ehat should I do?
