For 4 to 10 months, I've been ignored by 3 people who I thought that I was on good terms with. 

I'm trying to be forgiving because 2020 was so terrible. 

I feel really bad about my poor communication skills. I think my poor communication skills had something to do with this. 

I've tried to reach out to them, but, as of right now, I haven't had any replies. 

The lack of explanation is what I particularly feel pain about. What did I do wrong? 

 I hope these 3 friendships can be repaired someday. Who knows?
