He just froze up

Hi I'm a Libra. I started getting close with a Capricorn recently. We could talk for hours about everything. We seemed very in sync. Then recently we were talking about physical traits that attract us to potential partners. He admitted that he prefers“slim thick” girls with a flat stomach and firm bodies. I admitted to him that I don't fall into every description though he felt that I did, I dress well 🙂 He then became distant admitting that he was then afraid of hurting me and he should stop. When I ask "Stop What?" He just didn't respond. Matter Fact he said nothing after that. Why? Did I do something? He could have just said let's be friends and don't leave it open like that.

If he is really that shallow then I would not want him even as a friend. He can have his preference and is good that he does not want to lead you on but as Maya Angelou says

"If someone shows you who they are, believe them the first time"

Step back, you don't need someone around who would make you feel you were not enough for them. If you want to hang out with him ok but be careful.

Shallow and boring

Maybe he wanted to stop the conversation. He didn't want to hurt your feelings so that you don't feel that you don't fit the physical appearance he desires and feel inferior. Could be anything but just giving my 2 cents.
