Crush

I recently started sitting with a new friend group. I am really close to 3 girls. Starting to get close to 2 of them. And I'm not very close to 3 of them. It's a big group and there are always multiple conversations and I just never talked to 3 of them. We were talking about our crushes and I told them mine. I trust 3 of them. I sorta trust 2. But I don't really trust the other 3. And now they know. It's a big group and even though we agreed whatever is said in the circle stays in the circle I still feel like it'll leek out and then the drama and embarrassment will start. Should I say that I don't really like the guy or should I just trust?
