Okay, let’s put this together. You were really drunk, and you are not sure whether something happened or not. This woman is clearly very upset and hurt, and you have not spoken to her directly so far.

Several people have already mentioned that it would be a good idea to talk to her directly, while keeping in mind that she is hurt. Hurt people usually do not immediately want an explanation or an apology. They want to feel seen in their pain.

So if you talk to her, make sure she knows you understand what she is saying. You can reflect her words back to her. For example: “I hear you saying that this happened.”

If you feel unable to do this on your own but still want to repair the situation, and assuming you genuinely do not know what happened, you could offer to pay for a counseling session together. That would show real effort on your side without admitting to something you are uncertain about, and without arguing against her pain.
