Husband leaving for work tomorrow morning....

So my husband is leaving tomorrow morning to go work for Nabors again (an oil field company) and I am completely heart broken but happy at the same time. This is what he LOVES doing so I'm happy for him but sad because he'll miss out on so much.... Last time he worked we was only dating and no kids. He got laid off, we got married, and now we have a beautiful 6 month old baby girl... Ik he's doing this for us, but idk I'm just gonna miss him... And I'll basically be raising our daughter myself.... Also I secretly think I might be expecting again....
