I'm sorry to hear that you've been struggling with this. I too have gone through emotionally-driven "friend" purges, and I always find myself regretting it after the fact, but then feel too embarassed to go back and add these people again. I think it's normal to feel frustrated/hurt by being ignored that way. We are hard-wired social animals. But something in our culture has shifted; it seems like people - especially the younger generations - don't seem to have the social skills to handle each other. I once deleted a friend under similar circumstances, I had opened up and was then ignored and deleted him when I became hurt. I ran into him years later, and he told me how sad he was that I deleted him and that he just didn't know what the right thing to say would have been. My point is, you never know what they are thinking/feeling. It may just be that they don't have the emotional intelligence to respond to you. There's nothing wrong with your feelings, it makes sense to be upset by being ignored. But we're all just humans doing the best we can with what we know. Wishing you love and healing. <3
