That kind of rollercoaster (there then gone, there then gone - close then not close, etc) disturbs me too. (I know someone like this who I'm in a lull with on that roller coaster).

You say you're not sure what to do now. Do you mean for the holidays? Or with the friendship? Either way, I understand how difficult it can be to have a person be there and then not. For the holidays, maybe you can plan something special to do, just for you.
