I met a friend about 3 years ago, and even though we hit it off from the start, I was able to tell over time that she only thinks about herself.
For instance, recently, I was named in a lawsuit that should have been sent to my ex husband, and when I told her about it, she didn't seem to care. All she spoke about was about a guy that she liked. It was as if I had not mentioned anything to her. In fact, after I was thankfully dismissed from the case by a judge, she didn't even ask me what the results were.
Because of this, I decided to maintain my distance, because I noticed that she's of the type of person who loves to tell her stories and about her love adventures and everything regarding how much she hates her job, but doesn't really listen to anything anyone has to say.
Yet, a few weeks ago, I bought tickets to go to her home country for a holiday, and I casually told her about it, but she got very upset with me and asked me when I was planning on telling her. She basically told me that she was hurt about my lackadaisical attitude in keeping her informed.
I was surprised that she would even care about anything I had planned! I apologized for not informing her, but now looking back, I think that she was only upset at me because I was doing something that she wanted to do. I don't know how to explain it, but it's the way I feel, since she otherwise takes little interest in my personal life.
So my questions are two: First, what makes a person care only about themselves, and how should I go about this friendship, if I can even call it that?
