NEED ADVICE ASAP

So 2 of my best friends are both gay. 1 is in a relationship and the other isn’t.lets just say that friend A has a girlfriend and friend B doesn’t. Me and a large group of mates (them included) went to a party the other day and everyone got a little drunk. My 2 gay friends kissed each other. Word got out to almost everyone about it and I was getting more and more confused at who’s side of which story was true.

The way I see it, friend B shouldn’t have kissed friend A because she knew that A was in a relationship and she knew that A’s girlfriend is very protective. But at the same time, friend A kissed friend B back. Normally this would be the end of the story but friend B has sever depression and anxiety. She had also had a lot of alcohol and wasn’t in a fit mental state to be making rational decisions. Friend A was aware of B’s mental state so the way I see it they are both in the wrong.

• B shouldn’t have kissed A

• A shouldn’t have kissed B back because B was depressed, drunk and was not in a fit mental state.

• A also has a girlfriend (who is still unaware of what happened)

They are both my friends and I love them both dearly and I don’t want to loose either of them so please tell me what I am supposed to do. 😫
