Just because you feel bad afterwards and he didn’t call you back doesn’t make it rape.
I don’t know what he is suspected of doing. But I agree with you. Rape happens when it happens, not afterward when the woman regrets her choice. But going out with a man doesn’t equal ok to attack, neither does meeting for business in his hotel room, neither does serving you a drink. Naïveté or sexy clothes is not a license to force sex on someone.
Again, I have no idea of this accusation or behavior, just speaking in general.
