Is it okay to ask my bf for time apart/a break if

I feel like I am a lot more attached to him than he is to me? I feel like I’ve fallen head over heels. I’m scared he doesn’t feel the same. None of us have said the three words yet. I want to but I don’t want him to feel like he has to say it out of obligation. We’ve been together 8 months. He’s 25 and I’m 21. When we talk about the future he doesn’t really mention me. Just kind of himself and his goals. I dunno if I’m being too dramatic here though. My last relationship was with an abusive man so I don’t know if my gauge meter is ever appropriate or a result/response to my past. I got out of that relationship 2 years ago.
