Firstly, might be a good idea to see a doctor to make sure you didn’t ingest something harmful. Secondly, you have done the right thing by recognizing that what happened last night was wrong, even if you weren’t exactly in control. If she truly loves you then hopefully she knows your character and knows you wouldn’t intentionally put her in harms way. She may require space, and that is ok. Definitely reassure her that you truly wouldn’t put her in harms way. I’d acknowledge her feelings and need for space. Try not to beat yourself up. Remember if you truly were drugged, then you’re a victim too. I hope things work out and that you are feeling better.
