Am I in the wrong?

Okay. So I had a man rub up against me and even talk to me dirty when I was in a position that there was nothing I could do about it. I’m not saying he molested me. I think he was inappropriate with me. I told my boyfriend later and said I’m not looking for drama. I just wanted him to make me feel safe in a sense. I feel like I should be able to tell him stuff like that. Well the guy that rubbed on me and stuff decided to text me and I was polite so he would just go away. Well my boyfriend says “you gave me this whole watered down story of him basically molesting you and now you’re being polite?” And I was like I’d rather be polite so he goes away sooner. But I’m just upset at the fact that now I don’t think he ever believed me because he said I gave him a “watered down” story. Would you take it that way? I didn’t know the guy had my number or that he would text me. It’s not fair for him to be mad at me. I didn’t do anything.
