" But now it's been really weird because we barely talk anymore. "

"Now I barely ever hear from her. I called her once every 1-2 days for a little while but it's gotten to the point where she doesn't want to be on the phone anymore because there isn't anything to talk about"

" I'm sure it gets boring not saying much on the phone anymore after a certain amount of time. "

This......all screams "Danger! Will Robinson." to me. In a healthy relationship the amount you talk should be more or at least the same when apart.

My instinct tells me "it's over." You probably don't want to hear that but based on your description and my experiences a couple apart should communicate at least as much as when together...whether by voice, text, email, etc.
