Is NOBODY wrong in the post ? POST : I have three close friends I met 9 years ago in my first year of University. Let's call them A, B, and C. The three of them have been friends since grade school and A and B started dated late High School before I met any of them and were together for the first 5 years I knew them.  Then, 4 years ago they broke up. A now lives in a city a couple hours away, while B and C still live in the same city as me.  At Thanksgiving dinner C got really drunk and tore into me about inviting A to things. 

In particular he was referring to the fact A had come up for a wedding and crashed at my place. During that visit we made plans to go camping and invited B and C along with full disclosure A was going to be there. Because we all worked different hours we didn't arrive at the campsite together and shortly after A showed up, B got too awkward and left desite already drinking and us begging them to not drink and drive. 

Basically C said it is a personal attack against B that I still invite A to stuff and B takes it really hard then he has to comfort them and it's selfish of me to expect A and B to attend events together. Also, if B were to do something dangerous and get hurt (drinking and driving) due to being upset about it, that it would be my fault. 

I see where he is coming from but I have NEVER invited them to something without expressing the other has also been invited. I am hoping to have a New Year's dinner and wanted to invite both but now I am not sure? AITA for inviting both or WIBTA if I just invite one?
