I talked to someone today

I've been talking to someone online for the last two months, I have feelings for him, and he seems to have feelings for me, I'm not sure if it is too soon to have feelings from someone, specially if I haven't met him in person. I feel comfortable when I talk to him and today we were talking and somehow the subjet of me not being very expressive came up, and I ended up telling him that something bad happened to me in the past, and that It is hard for me to connect with people, I didn't have to say more, he immideatly understood of what I was talking about, someone close to him went through the same thing. I'm not sure if I was a good idea to tell him.
