Is AUTHOR wrong in the post ? POST : This happened a few months ago, but it's still not settled. Here goes:

My friend, who we'll call Beth, left town for a week to attend a funeral and some kind of memorial service thing that was a few days afterward. I didn't personally know the deceased, who we will call Sophie, but Beth was good friends with her before Sophie died in a car accident. A third friend in that circle who was close with both Beth and Sophie, who we will call Nick, also attended the funeral. 

Beth tells me that Nick left after the first funeral service, saying that he wanted to visit his girlfriend, instead of attending the memorial thing. 

I don't know really know Nick except from a few common social events. I didn't know Sophie before she died at all. So I can't presume to know what Nick was thinking or exactly how close he was with Sophie. So all I know is what he said to Beth before she told me:

Beth gave me the whole enchilada to eat at once and asked my opinion. She said that she texted with Nick after he left, that he replied in short sentences with little information or sharing, and that she told him he was letting Sophie's memory down and saying that he cared more about getting laid than about his dead friend. After she said these things to him, Nick stopped talking to her for good.

Beth said that Nick was being a huge asshole who was throwing away a friendship she thought was special. I said that he might be an asshole, but she was definitely too harsh with him if she wanted to remain friends. I said to her that accusing someone of not caring about their dead friend is enough to drive someone away, whether it's true or not. 

Beth thinks I was being an asshole for saying that, making excuses for bad behavior. Beth believes what she said to Nick was justified and that he's the asshole for cutting her off. 

AITA? I hope I explained this clearly enough.
