bro you can do better. way better.
now i have been, and am, in a similar position. and during those moments of emotion free clarity (or cried out clarity) i realise that i dont really want her back. i dont. neither do you.
imagine yourself walking down the street with this girl, hand in hand, or in bed getting sweaty, or walking on a beach, or whatever, knowing that this girl is not 100% dedicated to you. there is a seed of doubt in her mind as to whether or not she wants you. now and again, she will think "what if". big fucking "what if"s. the truth is, you love this girl more than she loves you. she doesnt see and acept you as her partner, she sees you as a prospective partner. a maybe. a possibly. because thats the truth. thats what you are. your ex has chosen the great unknown over you. imaginary men over you. strange dicks over you. she has embraced a whole new life...WITHOUT YOU IN IT...and she is happy with the decision. she thinks its the right thing to do.
oh of course she wants you as a friend. of course. youre a good bloke. youre safe. reliable. decent. caring. who the hell wouldnt want you around? hell i dont even know you and i want you here next to me. but at least she sounds like she realises that it isnt happening.
now im sorry i depressed you. youre probably still in that state of emotional flux, where a word or two from her spark hope and joy in your heart. thatll pass. the realisation that it just isnt happening, and in the back of your mind, that you dont really want it anymore, will slowly float to the top of your thoughts. kind of like a turd.
simple truth is that you want something that doesnt exist. she isnt what you thought she really is. your relationship isnt what you thought it really was. she is a stranger wearing a face, and speaking with a voice, that you love.
now honestly, go out and meet people. divert yourself. time doesnt heal, but it blunts the pain. memories recede. we all know that youre hurting. she knows youre hurting. her family knows that youre hurting. hurt isnt a choice. how you cope with it is.
cheers
