Advice needed?... How long in between time should I go when trying to contact him?...?

If I was in your position and I was in such a position once.. I would write all my feelings down on a letter.. and then later i would tear that letter up and not send it.. it seems if you tell him your feelings now.. nothing is going to change.. he and you have broken up...so if you want to remain friends.. and talk to each other on occasion I would not tell him because guys are like that if he knows you still have feelings for him and he doesn't reciprocate them other than feeling friendship for you, I think he will pull back altogether and not talk to you on the phone anymore.. if you write the letter it helps you to find closure.. pretend you are writing it to him and that you will send it .. but don't send it... He likes you a lot but obviously he wants to remain a friend.. so if that is too hard for you.. let him go altogether or accept to call him as a friend and talk to him as a friend but not as a GF would talk to him....xxx If you can do that, you won't lose his friendship but if you tell him I fear you will so I woudn't do it if i was you.. a good friend you can call when you want.. if you can call just as ''a friend''
