Help..

So I’m feeling guilty because I told my boyfriends bestfriend “love you” but I pacifically said in a friend way, and he understood that. He is one of my closest friends, but I just have this guilt feeling.. I’m not sure why, I need some reassurance- can you just comment your opinion? Like he is the sweetest guy I know. He use to like me- but I’m kind of freaking out. He told me he use to like me yesterday and he was giving me advice because I was upset yesterday, and I told him exactly this. “You’re such a good friend. Love you. (In a friend say of course)” he said it back though. I feel like I’m stressing over nothing just need some help that’s all!
