Is OTHER wrong in the post ? POST : On mobile right now so you know the rest.

My parents are going through a fucked up divorce right now and can have very little to do with each other without it blowing up into a huge fight. I'm with my mom for New Year's and at her friend's house. My mom didn't want me on the phone with him because she wanted me there to celebrate with her and didn't want my Dad associated with the situation. If I did call she would've been mad and I didn't want to be in the middle of that. Because she felt that way, being on the phone with him right then would've been a bad idea and would've caused an argument, so I was going to call him 10-15 minutes after midnight. He was mad about that and felt it unfair that he couldn't be on the phone with me at midnight. I then got to ring in the new year with a 1.5 hour long argument with my dad over the phone. Am I the asshole?
