i think sometimes it gets to the point when a friendship becomes hard work and tedious. Is this a sign that the friendship is no more?
somethings are best left in the past, as happy memories, fun times. what was once so great shouldn't be forced into the present or future, when other things have far exceeded their greatness.
friendships like other great things have a 'best before' date. after this date things begin to turn sour, and leave you feeling sick in the tummy. there is no reason, ever, to pursue something, which begins to affect your happiness and hurt your feelings.
I say be kind to yourself and respect who you are. it is up to you to make sure that the people who surround you are those who make you feel comfortable in yourself and safe. those who try to hack and pick away at you, and who make you question who you are as a person are no friends at all. rather fragments of your life best left behind, excluded from your mosaic, and left to dwindle into mere memories and dust.
