I've known her for several years, and she has always been self absorbed and a bit of a moaner but is getting worse and worse. We often go out in a group of friends, which is ok as obviously her behaviour is diluted, although she does dominate the conversation by talking about herself.
Basically she has one subject of conversation; 'her'! Whether it's moaning that she's cold, or moaning because she's tired, or talking about things that have happened to her, it's all about her. It is impossible to have a normal conversation with her where the conversation just flows as she goes over the same things over and over again and seems to have two or three main 'subjects' about herself and that's all she talks about. If I mention anything about myself or about current affairs or anything else, she doesn't reply. Or if I talk after she's been talking for ages she will busy herself with, for example, playing with her phone or rummaging in her bag. Today she popped round for a coffee and she was here for two hours and talked solidly about how cold she is (erm, we all are, it's winter!), how tired she is after doing extra hours at work this week, and about how she isn't sure whether to have her hair done a different colour or not.
To add a bit of background; she is in her late thirties but is totally spoilt by her parents, and in a way it's as if she's never totally grown up as she behaves in a total princessy way. She doesn't seem to 'get' that life is hard, everyone gets tired, everyone has problems, we just get on with it to an extent. Her parents have her child constantly for her, they do all her housework during the day when she's at work, they pay for everything for her, and treat her like a child.
I don't want to cut her off totally as our children are friends (that is how I met her) and have tried to distance myself but she never gets the hint. It would just be nice if sometimes she asked how I was, or listened if I spoke for a minute or two, or would have a chat about something other than herself!
