Boyfriend help. I'm 20F

So should I wait for my boyfriend to say I love you or should I say it first? I don't wanna be that clingy girlfriend but I'm pretty sure he's the one. We dated before, which ended in a mutual ending of the relationship because of what I was going through, but we've been dating again for a month and before that we were friends with benefits. We both never gotten over our feelings for each other.
