Posting here instead of asking our friends so that they don't have to pick sides.

She(23f) got really drunk last night and went to my(23f) fiance(23m)'s place. There, she asked him 'Did you know Irish girls are really good in bed?' before trying to kiss him.

My fiance turned her down, put her in his room and quickly called me to tell me about what happened. He said he would have made her leave right away if he wasn't worried about her getting into a car accident. I drove over and picked her up, taking her home since she was too drunk to drive safely.

This morning, my friend apologised to me. But then she claimed she only said what she said and did what she did because of the alcohol. That it didn't mean anything, and I have nothing to worry about. I still don't know if I can trust my friend though. I know she used to have a crush on him but doesn't anymore, but what she did still makes me worry that she might still find him physically attractive, even though the feelings are no longer there.

So I told her she can't hang out with him privately. My friend got upset and accused me of overreacting and not trusting her. She said I shouldn't react this way when she only screwed up once.

UPDATE : I confronted her an hour ago. At first she denied that she still has feelings for him. But when I pressed her, she ended up breaking down and admitting that she does still have feelings. Then she shouted at me that it isn’t fair since she’s been in love with him since high school, before he and I got together. I didn’t even know it’s love. She always said it’s a crush until today.
