<human>: Give me a shortened version of the text

I [21m] am trying to better understand the actions of my girlfriend [22f].  We've been dating for almost a year.

A few nights ago, we both went to a party.  We we're both good friends with everyone at the party, so we were mingling separately for a lot of the party.  She ended up getting pretty drunk.  Her and our good friend "James" we're in the kitchen (I was able to see them from the living room).  James is kind of a funny/creepy touchy person, so he put her arm around her - this didn't bother me at first, he was just kind of joking around.  But then they stayed in that cuddley position with their faces real close for like 10 min.  She seemed kind of into him.  It made me feel weird, but I didn't feel the need to step in - I guess I just wanted to see what would happen (I mean she knew I was right there).  Then they went outside to the shed (where there is a ping pong table) and played ping pong for a while.  She didn't acknowledge me throughout any of this.

When we got home, I told her I was really pissed off.  I thought her behavior was obviously totally weird and inappropriate.  She was super apologetic, and said she didn't think it was a big deal at the time since James was a mutual friend.

My question: Do most girls find this type of behavior acceptable?  I mean from the guys perspective, I think we all knew James was enjoying her company way too much, and would have loved to have had sex if the circumstances were different.  I don't know girls well enough to know if they would be able to see this too.

Also, it definitely seems like she was really loving the male attention, otherwise she wouldn't have let him wrap his arm around her for so long, right?

I'm kind of inexperienced with this stuff and I wanted to know Reddit's opinion of her behavior.
<bot>: GF was overly cuddley with a mutual friend at a party, I thought this was obviously inappropriate and was wondering if others agreed with me.
