Hmmm that really wasn't fair of him to say that. That response sounded like he doesn't care that you are graduation, but he probably does care and doesn't know how to respond to it.

Luckily your aunt will speak to him about it, and hopefully he will apoligize about how he has been reacting. Good luck

Sorry about what happened to your mum though, I sorta know what its like as my dad died when I was 11 years old.
