I have a friend who is divorced and has no children. I’ve enjoyed her company (well, kind of) over the years, but she does bang on about herself all the time and doesn’t even ask about my DH or family. She can’t seem to relate to my life, so I don’t talk about them, as if they don’t exist. I’m thinking of letting her friendship go as we’ve seen less and less of one another in the last few years and she’s forgotten to honour an arrangement to meet on more than one occasion. She has contacted me in the past to meet, or I text her, so I think that’s why I want to keep the friendship going, although we have less and less contact now. So it’s not all one-sided, but I think that friendships have a shelf life. Some perish quickly, some after a while, but the best ones can last a lifetime.
