I don’t think I’ll ever understand her reasoning behind her wishing to separate from me and a number of my friends who also know her well said the same thing. I do feel that what he wanted from a man changed and like you said she got “bored” and unexcited in being with me as she got older. When I last spoke to her she said that spark went. I’m guessing I’ll have to accept that there is nothing factual but emotionsl reason which can’t be explained.
