Friendship

So I recently lost my grandfather who was very near and dear to my heart 🥺 it’s really been hard on me , but a very close friend of mine didn’t reach out to me at all and that hurt me, I was there for her when she went through a lost. I believe someone that you consider a close friend should reach out but maybe other ppl think otherwise. It’s always seemed like

She only knew how to be a good friend when it’s time to party never when it matters most

Thoughts am I over reacting ?
