Would me telling a girl I like her push her away?

I was seeing a girl for about a month. We had a few great dates and seemed to get along very well. One night after a few drinks we were watching a movie in my room which eventually led to making out. After a while of that I asked her if she wanted to go any further and she said she wants to be sober when it happens. I tell her no problem and that her being comfortable is all I care about. She says she is comfortable and that she really likes me. Fast forward about a week, for whatever reason I decide to tell her how I feel and how much I like her. The unfortunate part is that after that things changed and I never saw her again. I don’t know if I said too much or said it too early or what I did. I never tried to date before this as I was focused on other things so this was my first experience dating. My eagerness may have taken over but I was really excited that I thought I had found somebody I enjoy spending time with. So did I scare her away?

Would me telling a girl I like her push her away?
