Friends not supportive

Lately I’ve been reflecting on my life (approaching 30) and those around me. I have a group of friends who I’ve known since highschool and we’ve always said that we’ll be there for each other and we talk everyday and sometimes see each other multiple times a week. Well, my grandma recently passed and I didn’t hear a word from them. My husband told all of them that she passed and I never got a call, text, flowers, nothing. I had another grandma who passed about 3 years ago and that was especially hard due to certain circumstances and I even went to the hospital from the physical toll it took. A few months after that I had a miscarriage and they all knew. Same thing, not a word was said to me, no visit to see if I was okay NOTHING. Looking back, I feel like I’m getting a lot of resentment because I never thought about it before. I was too busy dealing with family drama. But they are a group who are there for the good but when I truly needed them, it was crickets. Now I found out that I’m pregnant and I’m not even excited to tell them. I know everyone has life problems but I had support from everyone but them. I hate to have resentment but I care for them a lot so it hurts that they were not there for both loses. Like what can I count on them for. 😞
