Rose Anemone split, one half of it turned white

[Bolivian Reefer]

My Anemone split around a month ago, one half moved to a suitable position with light and the other stayed below the rocks. I figure to let it be until it moves by itself, that did not happened and now that other half has turned white and became smaller.

Last week I moved in order to put it under the light and this morning I noticed that it moved back under the rocks (where there is no direct light)

What can I do?

Thanks

Just leave it alone. BTA have a mind of their own. It will come out move if/when its ready. White it sounds like its not going to make it.. POst pictures..
