reducing "Friends" list

I am reducing my "FRIENDS" list.  To me a "friend" is one who contacts you, one you responds or corresponds with you, and shows a little bit of interest towards you.  Some have requested my friendship and never contacted me again. Some who used to be my "friends" have abandoned me, will not answer my hugs, nor my personal messages to them.  What hurts is, these were the ones who I thought were people that I did my best to help, to encourage and, show genuine concern and love for them. Some I have deleted because of no response to me.  I did not do this on a whim.  I have saw them on line, I have read their comments to others and read the hugs they have sent to others.  I know they have received my messages, my hugs, and yes, even my pleas for them to correspond with me.  I have almost begged them to message me, still I am ignored.  I have asked them to remove me from their friends list and they haven't done that either.  I really don't understand why I am treated like this.  All I have ever done is to try to help them and be a blessing to them.  I have never purposely tried to hurt anyone here on DS.  I have even apologized to these for whatever I might have done that I didn't know about and, still no response.  If you no longer want me for a friend or, want me corresponding with you, please remove me from your friends list and I will totally understand.  I mean, if you ignore me and never correspond with me, why do you have me for a "friend" anyway? I guess I am a dinosaur and you people just ignore me without caring how badly this hurts.  Oh well, I have a lot of scars so, I'll just add these to my collection.
