<human>: Can you give me a shortened version of the text?

My girlfriend texted me early this morning around 2AM that she and her friends (a bunch of drunk guys included) were going to play Truth or Dare. Since I was currently several hundred miles away from her I felt pretty apprehensive about it but I didn't want to ruin their fun, plus I trust her so I said I was fine with it.

Today she told me they only played for a few minutes before people started passing out due to the vast amounts of alcohol. I told her I was happy that was the case because I was nervous she might makeout with someone. She said I was overreacting and that "kissing and stuff like that is harmless if it doesn't mean anything, I would be fine if you made out with a girl if it didn't mean anything." 

We're now having a big argument and I'm unsure of how to proceed. I really care for her but obviously we have vastly different opinions on this. I told her "I don't want to makeout with other girls" and rather than saying something along the lines of "don't worry, I'm not going to kiss other people if it makes you uncomfortable" she merely said "and it's ok for you to feel that way!" 

Is this a bad sign that our relationship is doomed and that I should cut my losses and end it?
<bot>: Girlfriend believes it's ok to kiss and whatnot with other people as long as it doesn't mean anything. I majorly disagree.
