Hi Caroline, I think he puts a lot of expectations on your friendship, sometimes we have a friend but life goes on and the years pass and we realize that the friendship doesn’t resonate anymore and I think maybe its your case. I don’t think you should feel terrible with yourself but if you are not feeling this friendship anymore you should talk with him in a very honest way, its ok to grow apart and to understand that nothing last forever, he needs and will understand, you are both adults with your own life. I hope you are feeling better, sorry for my English its my 3 language.
