So me and a female co worker were working together. Today we were really playful and just having fun

She wanted to tell me something but was nervous to tell me, I wanted to know so kinda playfully joked that she should. She told me she finds me cute. I felt the same way but didn't say it back in the moment.

Later when it was time to go home, I told her I thinks she's pretty cute as well, left, gave a hug and went home

I feel like I messed up by telling her I find her cute as well though, like maybe I shoulda kept that to myself?

Idk what do you guys think?
