@Katia01,
What the hell are You feeling guilty about?
He made the advance, not you.
You pulled away and told him to stop.
You want to feel guilty over what someone else did?
What? Do you think you were supposed to be able to enter his thoughts and change whatever he was thinking?
You didn’t even make any kind of mistake. Apparently you were just sitting there.
What does your being drunk have to do with anything? Absolutely nothing.
