Off topic, but this reminds me of something that happened to me.
Long story short, I had to have a conversation over the phone with my ex-husband probably 10 years after we divorced. It was strictly a legal matter. By that time neither of us had any desire to have any conversation at all.
Can't remember exactly what he said, but at one point I had to say to him "Do you realize that I remarried about a year after we divorced? Like 9 years ago? You seem to think that my life just stopped."
What was really strange was that he had remarried as well. He was so self centered he couldn't imagine other people living their own lives.
To the OP, that reminds me of you. How many years have you been mooning over this person, and you don't know if she's even been available all this time.
