Ex-girlfriend is drunk. What should I do now lying in my arms?

You are happy to answer your questions.

First of all, where do you eat and drink now? At the hotel or at your house? Still at KTV? It depends on the occasion.

Of course, no matter what occasion, if your ex-girlfriend is drunk, wash her face first, then wake him up and give him a sip of alcohol. If she is outside, give her a room in the hotel and have a good rest. If she is at home, she should be sent home or have a good sleep at home.
