So today I spoke with my mother. She said that my father eventually got in touch with my brother. Apparently now my dad and my paternal grandmother will be flying to Italy for his graduation. She said he didn't sound upset, but he was mad at me because "He should have been the one to invite my dad and how I INVITED them." I really didn't INVITE my dad...I had a very general conversation with my dad and encouraged him to talk to my brother if he was interested in going.
My brother and I still haven't spoken. Nor do I plan on contacting him any time in the near future. Honestly, I feel like I have very little use for someone who speaks to me so disrespectfully over what was an HONEST mistake.
My mother, however, let me know that she EXPECTS we will have made up by Christmas because she doesn't want HER holiday ruined by OUR fight.
Sigh.
