Best friend ghosted me for two years. My dad died, then he finally gives me a response

Almost two years ago on my (26f) 25th birthday, my best friend (26m) didn’t show up to my birthday party and never answered any of my texts or calls from that point on. The day before he texted me happy birthday and said he would see me tomorrow but then just nothing. We have some mutual friends so I know he’s fine and he’s been hanging out with them just like normal. I definitely went a bit overboard but I texted him happy birthday both years since, sent him letters, left him voicemails, tried to reach out through mutuals just to get any sort of answer. About a month ago, my dad went into the ICU after suffering multiple strokes, sepsis, and kidney failure. I texted him about this a couple weeks ago because we knew each other for a long time and he knew my dad well. I didn’t get a response then so I didn’t really expect much but then my dad passed away this Sunday and I just felt like it was wrong not to let everyone who ever knew him know about it. Then a day or two later, I get this -.- I’m honestly just completely baffled how someone can be so self centered and completely okay with making my DAD DYING all about him. I literally dragged him out of depression pits multiple times and made sure he was taking care of himself so while I can kind of see his point, just feels like a cop out to me. Regardless of the reasoning tho, I really feel like now is not the right time and he could’ve easily just apologized. Like honestly it may be selfish but I don’t give a single sh*t about your issues when my dad just died and you could’ve told me you were feeling this way TWO YEARS AGO instead of just ghosting me.
