AIO if I want to cut ties with my friend because she didn't attend my grandpa's funeral

Me and this person have been close friends (or so i thought) for practically forever and when my grandpa died I only told her and 2 other really close friends. The other 2 friends attended the funeral but this person basically didnt even acknowledge the fact that they didnt come. They just asked me "oh wanna call?" (Knowing I HATE calls) and "want me to come over?" Thats all they said.

And since the day of the funeral I've been very dry with them and they asked me "you there" and "are u ok" (I'm obviously not ok my grandpa just died!!) But they haven't said anything about not coming for the funeral or anything. What makes me mad is the fact that this person always wants to go clubbing or partying or out somewhere, but cant take 10 mins of their time to come and pay respects? Or at least say something why they couldn't come but nothing. And it rubbed me the wrong way and showed me where their priorities actually lie.

Please tell me am I valid in how I feel or overreacting?
