Advice

A few months ago I (23F) was on a work trip by myself in a different state. I met a girl who was with the same company there and we went to get some food and went swimming in the hotel pool. She came back up to my room and tried to kiss me, i told her no and that I was in a relationship. She kept persisting until she pushed me onto the couch and started taking my pants off. I kept saying no but it was like my body was frozen, I just let her do what she was doing. When she was finished I started crying and she left. I tried to just forget about it, but it's still bothering me. I dont want to tell anyone about it because I wasnt more forceful, I said no but i didnt push her off or yell or anything.
