Yes absolutely, on both sides. I think a lot of it stems from just plain awkwardness really. I've made peace with it a long time ago, I think it can be really upsetting when you're younger because it makes you question your self worth but I think now that I'm in my mid-20s I've accepted that people will do it to you and you will do it to people and regardless of which end you're on, it's clearly for the best if one or both of you doesn't want to put effort into the friendship/relationship anymore.
