Relationship help? Anyone. Need it badly. 😖😖

Been dating this guy for 2 years, I rejected him before cuz we were close friends but I was in a bad place and he helped me through stuff and I game him a chance cuz I thought I was getting feelings for him. But now i feel like.. idk.. I made a mistake and we should’ve stayed friends.. we have good times together and I’m happy being around him.. but sometimes I just don’t even want to talk to him.. like he’s really annoying and it seems we don’t have as much in common as we use to cuz he’s changed.. and i feel like i hurt his feelings whenever I say something.. but i don’t wanna lose my friend.. also I don’t wanna break up with him then regret it afterwards cuz what if no one makes me as happy as he did every now and then..
