What would you do if your partner wants a separation but you are stuck dealing with everything?

She wanted the separation which I dont but it could help both figure stuff out but she has left me to pack up everything and take it to my new place even her stuff while she's out doing whatever and I am an emotional mess just going through this stuff am I selfish for feeling this way what do I say to her?
