Basically I met a girl at a bar last night and we had a decent conversation. I asked for her number and she said "I have a boyfriend so hopefully that doesn't change your mind"

I responded with a "no, let's exchange numbers anyway"

So we keep talking, kino is flowing pretty effortlessly because she's a bit drunk. At the moment, I didn't think much of it. But today, I woke up and realized that her being drunk basically meant that none of that was really significant.

How do I handle this? I'm not saying I want to be the reason she cheats so I'm just curious if there is anything you guys have done in similar situations because there was some interest but it may have just been because both of us were drunk that it went so well, which is why I'm not looking into it too deeply.
