She complains about not seeing you enough, yet goes to a bike show and doesnt invite you? That doesnt add up.

Just from what I've gathered, I think shes trying to send you signals that she wants out. The fact of the matter is, if she wanted to make time to be with you or call you, she would. I think shes holding something back and doesnt know how to break the news to you. You need to talk to her.
