<human>: Can you condense the text into a few key points?

Hey guys I'll make this short and sweet for you guys - we're both 18 years old and have been dating for about 3 months now officially, but seeing eachother for about 5 months now. We're seniors in highschool.

**Backdrop:** Right now she's in the Ukraine for a month to work out some dual citizenship thing. She's been gone for about two weeks now and we've been constantly skyping, texting, and calling despite the time difference

**The Dilema:**I told her I was going to a party of one of our friends and at first she protested claiming that I was sick a week ago and it wasn't good for my immune system (there would be alcohol there), we playfully argued about it for a bit and she eventually said she was fine with it, but I should still text her throughout the night - I agreed.

So throughout the night I kept texting her, but while I was there, and friend of mine (that's a girl) kept talking about how *I should break up with her and how she hated the fact I had a girlfriend*...she's not the nicest drunk. Either way she kept encouraging me to drink more and more until the point she said *"we should sleep together! not like sleep sleep, just sleep together!"*

And so I did. Nothing sexual happened at all. Clothes were still on and everything. I would compare it to brothers on a hotel bed.

So my question is: **should I tell my girlfriend about this incident?** I don't think it's a big deal, but I feel like it would be better coming from me then someone who witnessed it. On the otherhand, I wouldn't be very stoked if I found out my girlfriend had slept with another guy, even just as friends.
<bot>: I went to sleep in the same bed with a friend of mine that's a girl. Nothing happened between us, we just slept. Both girls don't like eachother very much - Should I tell my girlfriend?
