I know what to do really, I have to distance myself from her, and I have begun this process. I have a very one sided friendship with this person, we talk almost exclusively about her, she is retired but talks constantly about when she worked, when she went to uni, how clever she is. She is married with two grown up sons 40 and 38 who still live at home, no relationships. She is critical of my sons and my husband. She thinks it's terrible I look after my grandchild sometimes, she thinks that would be awful. She is so relieved she will never have grandchildren, she would hate the stress and the responsibility. I dread seeing her, she drags me down, I feel dejected after I have seen her. I have started reducing the amount of messages between us, keeping my responses short. I will see her less often. I am just wondering whether anyone else has any experience of detaching themselves from a friend who has become toxic to them.
