Moving on...

can i hold on to someone who no longer wants to be held? do i even need to hold on - am i just imagining that there's a pull away from me?
is someone replacing me? or am i just not needed anymore? would it feel less awful if I can blame someone and direct my anger towards that person? but can i really blame anyone? i can probably just accept it and move on, it hurts because someone else moved on, others might have been hurt when i was on the other side - when i moved on and they did not.. i probably didn't even spare a thought then, shouldn't i be equally nonchalant now? i so desperately want to do something, make things go back to the way they were, but i feel so helpless... they don't even realize... and i can see how this could become a self fulfilling prophecy.. my fears will make me think twice about every conversation, will lead to controlled emotions and artificial behavior... distances will widen...
