Very abbreviated version of the story:
I have 2 friends Liz and Adam. I'm better friends with Liz, though have been getting to know Adam a bit better recently. Can I just point out there is no problems with anyone fancying anyone here - it's all platonic friendships.
Basically, Adam told me the other day that he can't stand Liz anymore, she drives him crazy. They've had a bit of a history of arguments, big fights etc, and I thought everything was ok now. Liz thinks of Adam as one of her best friends, but he obviously isn't. I can see why Adam gets annoyed at her - she always acts differently around different people, trying to act all 'cool' and 'hard' and it does p*** a lot of people off. (Me included sometimes). Adam also said he's going to do something about this - there's a party coming up and he said he's going to "get wasted and let her have it" in his own words. Basically, their friendship is going to be over.
I really like both of them as good mates, and if they stop being friends completely it's going to wreck our whole group of friends and be completely awkward. I know Liz will expect me to stop talking to Adam as well, especially since we've only become good friends recently, but I'm obviously not going to do that. I don't know what to do - I don't want to fall out with either of them but things aren't looking good.
Any advice on what to do, if there is anything I can do?
