Give her some time, sounds like this reaction has come about fairly recently.
Also sounds like she think you are picking the trail over her, make it clear to her that is not the case.
Also dont forget about the fact it might scare the shi$ outta her that you will be gone for so long. She might be thinking "what if something happens to me, you, the house, car, how will I take care of these things?"
My wife just started cryn because I am leaving for my trip march 1st - sitting next to me right now, reading as I am typn. Her big worry is what if something happens to me or her and we are not there for each other.
She doesnt want me to go but like you, this has been something I have wanted to since around the age og 8 or so. She is willing to put up with it/support me
.
Keep talking to her and let her join in the WB site, might answer some questions/fears she has.
