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

Ok so my friend is a guy and his gf recently told him that she was pansexual and that she was talking to this other guy going on dates with him but not hooking up. My friend didn't really like the idea but thought he could accept it he wanted to meet the guy with his girlfriend because apparently he is pansexual also and his GF "was ok with it" but the guy refused to bring his GF into the situation. So my friend called Bs and and the GF dropped the boy toy. She told my friend that she would try only being with him one more time but she wasn't sure if it was going to work out. Now at our little kick backs we have every weekend She insists on playing spin the bottle and truth or dare. She is always kissing his best friend (no tongue only like one lip to lip 3 second kiss) but the BF is saying he is ok with it mostly because he doesn't want to lose her if i watch this for another minute i might just go apeshit i can't see one of my friend being put through this while we all watch Her cheat on him.  please all the feed back is appreciated i feel like drop her is the best option tho
<bot>: The GF found a cheap way of hooking up with other people without breaking her monogamous relationship and now one of my friends it going to suffer because of it
