Husband working away

First time husband has been away in years and this is our first baby and I’m so scared. He is in a 2 week on 1 week off rotation and it has been one day and I miss him like crazy already. Makes me want to Co sleep with my boy but we got him used to sleeping on his own 2 months ago and I don’t want to bring that habit back. I don’t know how I’ll be able to manage once he goes to his own room with husband working away. All I can say is I praise single moms cause its been one day and I already miss the help.
