<human>: Can you provide a brief rundown of the text in within 3 sentences?

I feel like shit and a total scumbag. Two days ago I went to hang out with my friend (mini backstory: we had a fwb type situation a couple of years ago, but I got over it long ago and have no feelings for him) and we ended up getting totally shitfaced. I mean, this is the drunkest I've ever been. I can remember almost nothing of the evening past a certain point. But apparently, my friend and I hooked up. I woke up the next morning missing clothes...*oh shit*. I left and went back to the place I'm staying and called my boyfriend (of about 1.5 years) to confess. I was crying and throwing up all day, this is the worst mistake of my life, I feel sick. I don't know how this happened, I never wanted it to happen. I wish with all my heart I could go back in time and erase this. I ruined everything.

Amazingly, he didn't immediately break up with me. After some consideration, he said he would give me another chance, and he believed he could still trust me. I promised not to drink ever again, since *I'm not myself* when I'm drunk. I know he says these things, and he's being unreasonably reasonable about everything, but...I still feel shitty. If he continues to decide not to break up with me, will this event taint everything in the future? I love my boyfriend so much, how could I have hurt him like this? For those of you who have been in a similar situation before, did it work out or was the relationship ultimately doomed to failure? Any words of advice or anecdotes would be appreciated. Thank you.
<bot>: I (VERY drunkenly) cheated on my boyfriend with a friend. I apologized profusely and he has not broken up with me but I am still disgusted with myself. Do we still have a chance?
