What’s the best way for me (30F) to let a guy (33M) know that I like him and want to take things further?

I apologize for the length of this, but I tend to overthink things, haha. I feel a bit silly writing this, especially since I’m not as young as I used to be, but I don’t actually have much dating experience. I was in one serious relationship before, which ended poorly. Currently, I’ve been casually dating a guy I met on Hinge for about 2.5 years, and we decided from the start to keep things fun without labels. I didn’t expect to develop feelings for him, but they’ve grown stronger in recent months. Now, I’m hesitant to bring it up because I don’t want to come off as “that girl.” We usually meet up 2-3 times a month due to our busy jobs and personal lives. When we do see each other, it’s for 6+ hours, filled with intimacy, dinners, movies, and deep conversations. I feel like we’ve built a genuine connection, but I worry that he might not feel the same way and that I could just be a placeholder. Despite it being over two years since we first discussed our situation, I haven’t brought up my feelings yet. Another thing that’s been on my mind is that we both still have our Hinge profiles. I’m not very active in updating mine, but I notice that he keeps his up-to-date. Since we're not in a committed relationship, I know it's okay, but it does seem to indicate that he’s keeping his options open. I haven’t said anything about my feelings for two reasons: one, I fear it will hurt to find out that he doesn’t feel the same, and I could just be a placeholder. The thought of that is disheartening. Two, I worry that if I bring it up and discover he doesn’t feel the same, I wouldn't be able to continue seeing him. That feels like the mature thing to do, knowing I’d be hoping for something that isn't on the table, putting him in an awkward position. Plus, I’d miss the intimate moments we share—which might sound selfish, but I’m human too. I recognize I’m overthinking this, and I’m aware I might be acting immaturely. Any advice would be greatly appreciated. I see a future with this man, and I really want to know how to express my feelings. TL;DR: How do I tell a guy I’m casually dating that I like him?
