So my SO got approved

Al

The marines approved him to join as long as he passed his asfab test. His misdemeanor from 5 years ago they said isn't a problem. He goes to indi (Indianapolis) to take the asfab here in like a week. Then he's signing his paper work and off to training. I'm so nervous but happy for him. Any tips to help with this transition? We've got a 10 mo and with him leaving for 4 months for basic it's going to be so strange. I'm so happy he's able to take this step but I'm already nervous about him being gone. How do you not go stir crazy ?? I'm currently a stay at home mom looking for work cause I've got my son in daycare so maybe working will help the time go by..
