Dude it's gaf, I am not.
Just send her a card or message on FB, you got your shit together OP. Again this is not fucking specialguy we are talking about (Just read that disaster of a thread).
Need a link to that thread.
And "let her be" advice could be given out of care for her as well.
She chose to lose contact with the OP.. she's given him no impression she ever wanted him to contact her again.. so in doing so he is violating the existing expectation.. it's not the end of the world but it's not as black and white as "I care therefore I should contact her."
Care enough to think about the complications of the scenario.
She tried to contact me often the first year we broke up, I never responded or acknowledge her.
